What researchers study
- Social-behavior and bonding research
- Oxytocin-receptor signaling
- Neuroendocrine models
Handling & storage
Supplied as a lyophilized powder for reconstitution with bacteriostatic water (not included). Store at −20 °C (−4 °F), protected from light. Every lot is independently tested against a 99%+ purity release target, and the batch Certificate of Analysis is published in full on this page.
Research Use Only (RUO). Not for human or animal consumption, nor for therapeutic, diagnostic, or cosmetic use; to be handled only by qualified professionals in a controlled research setting.
Identity and specification
Oxytocin is also referred to as OXT. It has the molecular formula C43H66N12O12S2 and a molecular weight of 1007.2 g/mol (CAS 50-56-6).
How this lot was tested
Every lot is tested by an independent laboratory before release. Our published certificate library covers the lots currently in stock; if a certificate for this product is not yet listed there, email us and we will send the one for your batch.
We use two independent laboratories, and each certificate says which produced it. Vanguard Laboratory is ISO 17025:2017 accredited (A2LA certificate #6377.01.01) and reports chromatographic purity and net quantity with a stated measurement uncertainty. Freedom Diagnostics reports HPLC-UV purity together with LC-MS identity confirmation, which is what verifies the vial contains the compound on the label rather than merely a pure something. Two laboratories, two methods, both published — see how we test.
Commonly studied alongside
In the literature Oxytocin is most often examined together with PT-141, Selank and Kisspeptin-10. Reconstitution is the same for all of them — see the reconstitution guide and the calculator, and the storage guide for how long reconstituted material holds. Current pricing for every compound and size is on the price list.
