UNSPSC 51422352: Melengestrol acetate

This classification denotes a therapeutic progestin with the molecular formula C25H32O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4W5HDS3936, chemically known as 17-hydroxy-6-methyl-16-methylenepregna-4,6-diene-3,20-dione acetate but more generally known as melengestrol acetate, which bears US NIH Compound Identifier 18020. Most nations, for tariff and trade purposes, schedule melengestrol acetate under HS 29372300 and SITC 54153. As of Q4 2014, MELENGESTROL ACETATE remains US FDA's Preferred Term for this commodity.

Melengestrol acetate bears US NLM identifiers UMLS ID C0025223 and NCI Concept Code C74577. SMILES: CC1=C[C@@H]2[C@H](CC[C@]3([C@H]2CC(=C)[C@@]3(C(=O)C)OC(=O)C)C)[C@@]4(C1=CC(=O)CC4)C.

UNSPSC 51422352 Melengestrol acetate is a Commodity code that appears in state and local procurement records but shows minimal alignment with actual buying activity. The single recent opportunity tagged under this code—Seminole County, Florida's IFB60459723LAS for naloxone and drug deactivation systems—does not match the pharmaceutical compound named in the code. Melengestrol acetate is a progestin used in veterinary and livestock applications, whereas the Seminole County solicitation targets opioid-reversal and drug-disposal products for community health support, a categorically different product line that suggests either a data-entry error or a coding mismatch in the sourcing system.

Seminole County's naloxone procurement, posted June 30, 2026 with a response deadline of July 26, 2023 (an apparent date conflict in the source record), sought annual supplies of 1,900 units of naloxone and 800 safe drug deactivation systems through competitive sealed bid, with quarterly deliveries to the county community health building in Sanford. The contract included a two-year initial term with a one-year renewal option, drug-free workplace and E-Verify requirements, and potential FEMA funding with associated federal compliance obligations. No other recent state or local opportunities appear under this code, indicating either very limited procurement volume or systematic coding misalignment. Business development professionals should verify whether their product line matches the melengestrol acetate nomenclature or whether opportunities in veterinary-pharmaceutical procurement would be better pursued under alternate UNSPSC codes or through direct market research in county and state health department channels.
