Verifying Oxytocin starts with the catalog SKU, not the compound name. Confirm the listed code, the nominal milligrams in each vial, and how many vials are in the pack, then open the certificate of analysis (COA) that names that same SKU and batch. The product page lists three pack variants, and published certificates exist for one batch of each; those certificates describe only the tested lots.
Listed SKUs, vial size, and pack quantity
The Oxytocin product page records CAS 50-56-6, molecular formula C43H66N12O12S2, and molecular weight 1007.2 as catalog identity. Public listed variants on that page are:
| SKU code | Nominal size per vial | Vials per pack |
|---|---|---|
| OXY2(OT2) | 2 mg | 10 |
| OXY5(OT5) | 5 mg | 10 |
| OXY10 | 10 mg | 10 |
That SKU list is limited to publicly listed variants and is not a claim that the catalog is exhaustive.
Editorial guidance on per-vial size versus pack quantity treats per-vial size, vials per pack, and pack price as three separate fields. A description such as 10 mg × 10 vials means ten vials with a nominal size of 10 mg each; it is not a single vial containing 100 mg. The sum across one pack is label arithmetic, not an analytical measurement. Actual fill and peptide-content measurements belong to the particular batch report. If a quotation uses a different packaging description, ask support to reconcile it before relying on the calculation.
Batch COA evidence by SKU
The three published Oxytocin certificates below are recorded results for those batches only. They are not evidence of every batch or of clinical suitability. Provider verification links were not independently fetched.
OXY2(OT2), batch A9P6TU0JDPYV. The OXY2(OT2) batch record lists certificate QC-2026-L9VNUQA9HZ, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), and test date 2026-05-15, with SKU size 2 mg. The analyte on every row below is Oxytocin OXY2(OT2).
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 1007.2 +/- 1.0 Da | 1006.5 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.7 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 91.9 % | Pass |
| Actual fill | Gravimetric | 2 mg | 2.16 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 5.1 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
OXY5(OT5), batch BR53VXL4G327. The OXY5(OT5) batch record lists certificate QC-2026-J45TDJFA9A, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), test date 2026-05-15, and SKU size 5 mg. The analyte on every row below is Oxytocin OXY5(OT5).
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 1007.2 +/- 1.0 Da | 1006.5 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.5 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.1 % | Pass |
| Actual fill | Gravimetric | 5 mg | 5.44 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 5.4 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
OXY10, batch 35Z68352T8RP. The OXY10 batch record lists certificate QC-2026-2F52NV8WSR, laboratory Stand Science & Technology Pharmaceutical (Qingdao) Co., Ltd. (Stand Group), test date 2026-05-15, and SKU size 10 mg. The analyte on every row below is Oxytocin OXY10.
| Item | Method | Specification | Result | Determination |
|---|---|---|---|---|
| Appearance | Visual | White or almost white loose powder | White loose powder | Pass |
| Mass spectrum | MS | 1007.2 +/- 1.0 Da | 1006.5 Da | Pass |
| Purity | HPLC | NLT 98.0 % | 99.2 % | Pass |
| Peptide content | HPLC | NLT 90.0 % | 92.7 % | Pass |
| Actual fill | Gravimetric | 10 mg | 11.90 mg | Pass |
| Water content | Karl Fischer | NMT 8.0 % | 3.7 % | Pass |
| Bacterial endotoxins | LAL (gel-clot) | NMT 10 EU/mg | <3 EU/mg | Pass |
Gravimetric actual-fill results (2.16 mg, 5.44 mg, and 11.90 mg) are batch measurements against the nominal 2 mg, 5 mg, and 10 mg specifications. They do not change the catalog SKU size and are not a fill figure for untested lots. An endotoxin result is not a sterility result.
Matching SKU, batch, and certificate
A SKU identifies a listed product variant; a batch number identifies a batch record. Use both when locating a COA. Compare product name, SKU, batch, and certificate number. Open the product page, select the SKU, and read the matching certificate panel. A report for one size should not be used as evidence for another size merely because both say Oxytocin. An older published batch is not evidence of the batch that will be shipped next. A missing public result is not automatically a failed test, and it is not a passed test either.
Editorial COA verification guidance starts by matching product name, SKU, and batch number, then comparing certificate number and test date with the original report. Seeing a verification link alone does not prove that a report is currently valid; a provider page may require an account, and the site does not independently confirm the current status of a login-protected record. 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 published report does not mean every order receives that batch; confirm the batch allocated to the order separately.
Verification checklist
- Match the product name Oxytocin and the exact SKU (OXY2(OT2), OXY5(OT5), or OXY10).
- Confirm nominal size per vial (2 mg, 5 mg, or 10 mg) and 10 vials per pack as listed on the product page.
- Record the batch number and certificate number from the matching COA page.
- Compare each row's analyte, method, specification, result, units or qualifiers, and recorded determination with the original report.
- Do not apply an OXY2(OT2) certificate to OXY5(OT5) or OXY10, or the reverse.
- If the allocated batch is not stated or a public result is missing, ask support for that SKU and batch rather than substituting another lot.
Frequently Asked Questions
Does SKU OXY10 mean one vial that contains 100 mg?
No. OXY10 is listed as 10 mg per vial and 10 vials per pack. A 10 mg × 10 vials description means ten vials with a nominal size of 10 mg each, not a single 100 mg vial.
Can a COA for OXY2(OT2) be used as evidence for OXY10?
No. A report for one size should not be used as evidence for another size merely because both say Oxytocin. Match product name, SKU, and batch number.
Do the published Oxytocin batches ship with every order?
No. A published report does not mean every order receives that batch. Confirm the batch allocated to the order separately.
What if a public Oxytocin COA is missing?
A missing public result is not automatically a failed test, and it is not a passed test either. Ask support for the exact SKU and batch rather than substituting a different lot.
