Oxytocin (Research Grade)

Oxytocin is a nine-amino-acid cyclic neuropeptide produced in the hypothalamus, with a disulfide bridge between residues 1 and 6. It is the primary tool compound in social bonding and neuroendocrine signaling research.

Oxytocin specifications

Reference data researchers look up before ordering oxytocin. Every lot ships with documentation matching the batch number printed on the vial.

  • Class: cyclic nonapeptide hormone
  • Structure: intramolecular disulfide bridge
  • Common route: intranasal
  • Storage: -20°C lyophilized

Oxytocin purity testing and certificate of analysis

Each oxytocin lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.

  • ≥99% HPLC purity specification
  • LC-MS mass confirmation on every batch
  • Endotoxin and sterility panel documentation
  • Lot-matched oxytocin COA published on the certifications page

Oxytocin reconstitution and BAC water ratios

Oxytocin ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.

  • 10mg vial + 2mL BAC water = 5mg per mL
  • Transfer to a metered pump for intranasal protocols
  • Sensitive to heat — never leave at room temperature
  • Refrigerate after reconstitution

Where to buy oxytocin

PX1 Research synthesizes and fills oxytocin in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Frequently asked questions

Why is oxytocin usually intranasal in research?

Intranasal administration is the standard route used in the CNS literature because peripheral oxytocin crosses the blood-brain barrier poorly.

How should oxytocin be stored?

Lyophilized at -20°C, and refrigerated at 2–8°C once reconstituted. It degrades quickly at room temperature.

Is a certificate of analysis provided with oxytocin?

Yes. Every oxytocin lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.

How should oxytocin be stored?

Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
