Alprostadil's molecular classification in the catalog

The technical catalog describes Alprostadil as a synthetic prostaglandin E1. That classification comes from the eicosanoid family — signaling lipids derived from fatty acids — not from the peptide family that groups most references on this site. The difference matters for anyone building a lab file: grouping Alprostadil with peptides by price or commercial-category proximity would be a chemical classification error, not merely a catalog one.

This page does not describe any effect of Alprostadil in an organism, nor does it compare the reference with an approved medication. The content is limited to what the catalog states: name, structural family, presentation, reference price, and documentary conditions. Any additional data — sequence, formula, or mechanism — stays off this page unless a verifiable source supports it.

Its place among the catalog's classic hormones and cofactors

Within the curated category "Classic hormones and cofactors," Alprostadil shares space with seven other references: Acth 1-39, EPO, Glutathione, Insulin, Melatonin, Oxytocin Acetate, and Vitamin B12. Not all of them are peptides: Melatonin is an indolamine and Vitamin B12 a cobalt compound, just as Alprostadil is a prostaglandin. What brings the group together is not chemical structure but the fact that these are molecules with long-standing characterization in the technical literature, unlike more recently synthesized peptides.

Alprostadil, with its 20 ug presentation, shares a commercial group with peptides of greater declared mass, such as EPO or Insulin, even though its classification as an eicosanoid bears no structural relation to any of them. Each reference's current price is always confirmed in its own commercial block, independent of the declared milligrams or micrograms.

Microgram presentation: what changes versus a milligram

Alprostadil's specification is declared in micrograms (20 ug), not milligrams. A microgram equals one thousandth of a milligram, so the compound's mass per vial is considerably smaller than that of most peptides in the catalog, which come in ranges of 1 to 100 mg. Because it is a declared mass rather than a volume in milliliters, this reference's physical form is lyophilized powder in a vial, following the same criterion the catalog applies to any presentation measured by mass.

That microgram scale does not change the lot's documentary conditions: identity and purity still cannot be presumed from the name or the presentation, and are confirmed through the corresponding certificate of analysis. Nor does it change the storage condition declared by the site, which applies equally to all lyophilized-powder presentations in the catalog.

Alprostadil versus other non-peptide references in the same category

Within its own category, Alprostadil can be compared, in strictly structural terms, with Vitamin B12 and Melatonin, the other two non-peptide references in the same group. Alprostadil is a lipid derivative (prostaglandin E1); Vitamin B12 is a cobalt compound (cyanocobalamin); Melatonin is an indolamine (N-acetyl-5-methoxytryptamine). The three share a catalog and a research-use framework, but not a chemical family or mechanism, and this page does not claim that they do.

Against the peptide references in the same category — Acth 1-39, EPO, Insulin, Oxytocin Acetate — the difference is even greater: those are amino-acid sequences, and Alprostadil is not. Keeping that distinction clear in the purchase file avoids classification errors when an institution organizes its inventory by molecular family rather than by commercial category.

Alprostadil's certificate of analysis: Janoshik, HPLC, and mass spectrometry

The certificate of analysis (COA) for each lot of Alprostadil is issued by Janoshik Analytical, the laboratory Péptidos Colombia works with for the documentary verification of its references. The report states purity by HPLC (high-performance liquid chromatography) and identity by mass spectrometry (MS). This page does not reproduce a purity figure, because that figure belongs to each specific lot's report, not to the reference in general.

The COA is handled on request and subject to documentary availability. Upon receiving it, verification should confirm that the reference name and the lot identifier match the material shipped. CAS number, formula, and molecular weight are not filled in on this page: if an institution's file requires them, they should be requested as additional data and verified against a documentary source of the institution's own, not against this commercial description.

Storage, shipping, and closing the quote

Alprostadil is stored according to the documentation applicable to the lot; when that documentation specifies 2–8 °C and protection from light, those conditions must be built into internal custody before shipping arrives. Shipping rates for Bogotá and for the rest of the country are shown separately from the product price on the site's shipping information, so the budget stays auditable. Delivery times are confirmed at the time of quote. 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.

The site does not charge at the moment a reference is selected: the request is registered first, the quote is then confirmed in writing with presentation, price, shipping, and payment method, and only then is payment coordinated. The purchase file is more complete when it keeps, in order, the accepted quote, the payment receipt, the shipping confirmation, and the lot's COA if it was requested.
