Information for institutional quotation
Oxytocin Acetate: price, documentation and dispatch in Colombia
Oxytocin Acetate is available in three presentations — 2 mg, 5 mg, and 10 mg — within Classic Hormones and Essential Cofactors. Technically it is a cyclic nonapeptide with a disulfide bridge: a ring-shaped structure closed by a sulfur-sulfur bond, unlike most of the linear peptides that dominate the catalog. This page explains that structure, places the price of all three presentations within its category's range, and details the role of the Janoshik Analytical certificate, which confirms identity and purity per batch. The material is distributed exclusively for research and institutional B2B quotation.

The price above is the public value per vial. Availability and batch documentation are confirmed before the quotation is accepted.
Three presentations of the same cyclic nonapeptide
The catalog offers Oxytocin Acetate in 2 mg, 5 mg, and 10 mg. All three share the same structural classification; the difference is the declared mass per vial, which sets the list price for each line item. For an institutional quotation, the exact presentation should always accompany the reference name, so that the request and the receiving record match unambiguously across the three options.
Being a nonapeptide means the sequence has nine amino acids; "cyclic with a disulfide bridge" adds that the sequence closes on itself through a bond between two sulfur atoms, forming a ring rather than an open chain. That combination — length and cyclic shape — is what this catalog's technical sheet states for this reference.
The disulfide bridge: an uncommon structure in this catalog
Most peptides in this catalog are linear chains. Oxytocin Acetate's disulfide bridge sets it apart from most of its category neighbors: ACTH 1-39, Alprostadil, Glutathione, Melatonin, and Vitamin B12 do not share that cyclic structure. The partial exception is Insulin, classified in the catalog as a two-chain protein joined by disulfide bridges: a different structure — two separate chains, not a single ring — but one that also depends on that same type of bond.
This page notes that bond-type overlap between Oxytocin Acetate and Insulin only as a structural classification detail, verifiable in each one's technical sheet. It does not imply a functional relationship or a shared molecular family between the two references.
Three Oxytocin Acetate presentations: what to state in the quotation
Classic Hormones and Essential Cofactors groups well-characterized references: ACTH 1-39, Alprostadil, EPO, Glutathione, Insulin, Melatonin, Oxytocin Acetate, and Vitamin B12.
The current price for each of Oxytocin Acetate's three presentations — 2 mg, 5 mg, and 10 mg — appears separately in the pricing block on this page and should be confirmed there before approving any quotation, without assuming it matches another reference in the same category.
Confirmation by MS and HPLC for a cyclic structure
Oxytocin Acetate's COA is issued by Janoshik Analytical, per batch, with mass spectrometry (MS) for identity and high-performance liquid chromatography (HPLC) for purity. For a cyclic structure with a disulfide bridge, identity confirmation by mass is a particularly relevant data point, because it distinguishes the closed ring form from an open chain of the same sequence.
The certificate is handled on request and subject to documentary availability. CAS number, molecular formula, molecular weight, and the exact purity percentage are not filled in this text: they remain visibly pending in the technical block, referred to the document of the dispatched batch, for any of the three presentations.
Storing the lyophilized powder according to the chosen presentation
All three presentations are declared by mass, so Oxytocin Acetate corresponds to lyophilized powder in a vial regardless of which of the three is chosen, with declared origin in the United States. Shipping cost is the same regardless of the chosen presentation; see the site's shipping information for current rates to Bogotá and the rest of the country. This page does not set delivery timeframes: they are confirmed at the time of quotation, depending on the presentation requested and the destination. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
Storage follows the documentation applicable to the batch; when it specifies 2–8 °C and protection from light, that condition applies equally to all three presentations, and should be ready at the receiving institution before the package arrives.
Recording the order from quotation to receipt
An Oxytocin Acetate order, in any of its three presentations, does not trigger an automatic charge: the request is registered, the quotation is confirmed with the payment method and total defined, and only then is payment coordinated. The chosen presentation should be explicit in every document in the process.
The final file can bring together the quotation, payment, dispatch, receipt, and the Janoshik COA if it was requested. This page is limited to that documentary chain and to Oxytocin Acetate's classification as research material, without extending its scope to any other use.
Frequently asked questions about Oxytocin Acetate
What presentations does Oxytocin Acetate come in?
2 mg, 5 mg, and 10 mg. The list price of each appears in the pricing block on this page and is confirmed in the institutional quotation.
What does it mean that it is a cyclic nonapeptide with a disulfide bridge?
That its sequence has nine amino acids and closes into a ring through a bond between two sulfur atoms, unlike most of the catalog's linear peptides.
Who certifies Oxytocin Acetate's identity and purity?
Janoshik Analytical, per batch, with MS for identity and HPLC for purity. The COA is handled on request and subject to documentary availability.
What other catalog reference has disulfide bridges?
Insulin, classified as a two-chain protein joined by disulfide bridges. It is a different structure from Oxytocin Acetate, which is a single ring.
How is Oxytocin Acetate stored?
As lyophilized powder, in any of its three presentations, per the documentation applicable to the batch. If it specifies 2–8 °C and protection from light, that condition is built into the custody record.
