How to Read a Oxytocin Acetate Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For Oxytocin Acetate, the informative checks are not the same as for a generic short peptide.
In plain English
Confirm the weight near 1007.2 for the intact loop. The critical extra check is whether any material appears at roughly double that weight — that means two molecules have joined together through swapped sulfur bonds. Purity percentage alone can look fine while that is happening.
What Oxytocin Acetate actually is
Oxytocin is a natural hormone made in the brain, familiar from research on social bonding and childbirth. It also holds a place in chemistry history: it was the first hormone of its kind ever built synthetically, in 1953, and that work won a Nobel Prize two years later.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for Oxytocin Acetate
What to check on the COA
Confirm the molecular ion at 1007.2 Da for the intact cyclic monomer. The critical additional check is dimer content: a species at roughly twice the monomer mass indicates intermolecular disulfide exchange. Purity by HPLC alone can look acceptable while dimer accumulates, so the mass spectrum matters here more than for linear peptides.
Disulfide-linked dimers, deamidated species (+1 Da), and reduced open-chain forms.

What Oxytocin Acetate is studied for
The largest behavioural-neuroscience literature of any peptide in this catalogue.
Studied for interactions with cortisol and stress-response signalling.
Its originally characterised role, and the basis of its clinical history.
Oxytocin and vasopressin differ by two residues, and receptor cross-reactivity is a persistent methodological theme.
