Oxytocin is a nonapeptide with the sequence Cys-Tyr-Ile-Gln-Asn-Pro-Cys-Leu-Gly-NH2, with a disulfide bridge between the two cysteines. PubChem lists its molecular formula as C43H66N12O12S2, with a molecular weight of about 1007.2 g/mol. It was the first peptide hormone ever synthesised.

KYVEC supplies Oxytocin as a lyophilised (freeze-dried) powder in a sealed, labelled vial, packed in our signature KYVEC black box. Each label shows the product name and quantity, so stock can be logged and tracked in your lab inventory as soon as it arrives.

Storage and handling: Store unopened vials in a cool, dry place away from light. For long-term storage, refrigerate (2–8°C) or freeze (−20°C). Once reconstituted for laboratory use, keep refrigerated and avoid repeated freeze–thaw cycles. Handle with standard laboratory PPE.
