Verifying Frag 17-23 means matching four separate facts: the listed SKU, the nominal size of each vial, how many vials are in one pack, and the certificate of analysis (COA) issued for a named batch. A product name by itself is not enough when more than one size or batch can exist. Start from the public product listing, then open the matching batch page, and treat site reading guides as editorial help rather than independent scientific evidence.
Listed SKU, vial size, and pack quantity
The public Frag 17-23 specification lists SKU FRAG10, with a nominal size of 10 mg per vial and 10 vials per pack. That view covers publicly listed variants only and is not a claim that the catalog is exhaustive.
Read those fields the way the site's vial-size and pack-quantity guide describes them: per-vial size, vials per pack, and pack price are three separate values. A description such as 10 mg × 10 vials means ten vials, each with a nominal size of 10 mg. It is not one vial that contains 100 mg. Any pack total obtained by multiplying size by vial count is label arithmetic, not a laboratory measurement. Actual fill and peptide-content results belong only to the particular batch report.
| Field | Listed value |
|---|---|
| Product | Frag 17-23 |
| SKU | FRAG10 |
| Nominal size per vial | 10 mg |
| Vials per pack | 10 |
| Nominal sum across one pack | 100 mg (label arithmetic only) |
CAS number, molecular formula, and molecular weight are recorded as unknown on that product specification. Unknown is not a measured value, a pass, or evidence that those identifiers were confirmed.
Before ordering, the same guide recommends matching the exact product and SKU, checking the per-vial size and unit, checking the number of vials per pack, setting the number of packs required, and reviewing matching batch records. If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation. Selecting a different SKU can change pack price and available stock. The product page shows the price of one listed pack, and checkout confirms the order total. A saved screenshot can become outdated when prices or availability change.
Published batch COA for SKU FRAG10
A SKU identifies a listed product variant, and a batch number identifies a batch record. Use both when locating a COA. Do not treat a report for another size as evidence for FRAG10 merely because both are labeled Frag 17-23. An older published batch is not evidence of the batch that will be shipped next.
One published record is Frag 17-23 batch FWC3Y325A33L. That page records certificate QC-2026-5UWHGGNJJX, SKU FRAG10 at 10 mg, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), and test date 18 August 2026. The record's scope is the published results for this batch only. Provider verification links were not independently fetched. The record is not evidence of clinical suitability or of every batch.
Summary lines on that COA include Identity Conforms, Purity 98.8 %, Weight 11.79 mg, and Endotoxin <3 EU/mg, each marked pass in the summary. Item-level tests for analyte Frag 17-23 FRAG10 are recorded as follows.
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | Corresponds to theoretical mass | Conforms | Pass |
| Purity | HPLC | NLT 98.0 % | 98.8 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.0 % | Pass |
| Actual fill | Gravimetric | 10 mg | 11.79 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 3.4 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Keep those analytes, methods, units, qualifiers, and determinations as written. The gravimetric fill of 11.79 mg is the recorded result for this batch; it is not a substitute for the catalog's nominal 10 mg size, and it does not describe other batches. An endotoxin result is not a sterility claim. Mass-spectrum Conforms is the recorded identity line for this certificate, not a completed CAS or formula assignment on the product page.
How to verify without mixing SKUs or batches
The site's COA verification guide starts with product name, SKU, and batch number. Open the original report and compare its certificate number and test date with the summary, then use the verification link for that report. A verification page may require an account with the report provider; seeing a link alone does not prove that a report is currently valid. This website does not independently confirm the current status of a login-protected record.
A practical sequence from that guide is:
- Read the product and SKU from the product page or order documentation.
- Find the batch in the published lab-report listing. If the allocated batch is not stated, ask support to confirm it.
- Open the batch page and check the certificate number, sample identity, test date, and listed laboratory.
- Open the original report and compare the values and units with the summary.
- Follow the report-specific verification link. If the provider requests login or the record cannot be confirmed, resolve that with the provider or support before treating verification as complete.
If details differ, do not substitute a report for a similar product or a different size. Send support the SKU, batch number, and the specific difference. A screenshot can help comparison, but the original document and provider record are stronger verification evidence.
If a public result is missing, ask support for the exact SKU and batch. A missing public result is not automatically a failed test, and it is not a passed test either. If a previously shared report link is no longer available, ask support for the current documentation rather than substituting a different batch.
Checklist for Frag 17-23 documentation
- Confirm the product name is Frag 17-23.
- Confirm SKU FRAG10 on the product listing.
- Confirm nominal 10 mg per vial and 10 vials per pack, read as ten separate vials.
- Do not treat a 100 mg pack total as a single-vial fill or as a COA result.
- Match batch FWC3Y325A33L and certificate QC-2026-5UWHGGNJJX only when that is the allocated batch; open the published batch page to compare fields.
- Compare each COA line (appearance, MS, HPLC purity, peptide content, gravimetric fill, Karl Fischer water, LAL endotoxin) with the original report, including units and qualifiers such as <3 EU/mg.
- Treat unknown CAS, formula, and molecular weight as unknown.
- Confirm the allocated batch separately; a published example is not a promise that a future order receives that batch.
Frequently Asked Questions
What SKU and pack layout are listed for Frag 17-23?
The public listing shows SKU FRAG10, a nominal 10 mg per vial, and 10 vials per pack. That view covers publicly listed variants only and is not a claim that the catalog is exhaustive.
How should 10 mg × 10 vials be read?
It describes ten vials with a nominal size of 10 mg each, not one vial containing 100 mg. The pack sum is label arithmetic, not an analytical measurement. Actual fill and peptide-content figures belong to the particular batch report.
Does batch FWC3Y325A33L apply to every Frag 17-23 order?
No. Those published results apply only to batch FWC3Y325A33L and SKU FRAG10. Confirm the batch allocated to the order separately; a published report is not a promise that a future order receives that batch.
What purity, peptide content, and fill were recorded for FWC3Y325A33L?
For analyte Frag 17-23 FRAG10 on certificate QC-2026-5UWHGGNJJX: HPLC purity 98.8 % (specification NLT 98.0 %), HPLC peptide content 92.0 % (specification NLT 90.0 %), and gravimetric actual fill 11.79 mg (specification 10 mg), each recorded as Pass.
What if no public COA is shown for my SKU and batch?
Ask support for the exact SKU and batch. A missing public result is not automatically a failed test, and it is not a passed test either. Do not substitute a different size or an older batch.
