UNSPSC 51287003: Chaulmosulfone

This classification denotes a topical anti-infective agent with the molecular formula C48H76N2O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 1S50W1WU8T, chemically known as 4,4-sulfonylbis-(cyclopentanetridecananilide). but more generally known as chaulmosulfone, which bears US NIH Compound Identifier 193966. European Medicines Agency schedules Chaulmosulfone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07462MIG.

The term CHAULMOSULFONE is an International Non-Proprietary Name or INN (see World Health Organization INN reference publication, Volume 16, No. 3 1962, List 4). CHAULMOSULFONE is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: S(=O)(=O)(C1CC(CC1)CCCCCCCCCCCCC(=O)NC1CCCCC1)C1CC(CC1)CCCCCCCCCCCCC(=O)NC1CCCCC1.

UNSPSC 51287003 Chaulmosulfone is a Commodity code that, based on recent state and local solicitations, does not reflect the actual procurement activity tagged under it. The opportunities posted under this code involve naloxone procurement, medical and first aid supplies for emergency response, generic pharmaceuticals and over-the-counter products through cooperative purchasing, and pharmacy benefit program initiatives — none of which align with chaulmosulfone, a pharmaceutical compound historically used in leprosy treatment. State and local governments are soliciting emergency medical supplies, naloxone for overdose response, and generic pharmaceutical sourcing through health departments, fire departments, and cooperative purchasing consortia, but the chaulmosulfone code appears to be a categorical misclassification rather than an active procurement category. The issuing bodies include county health departments (Seminole County, Florida), municipal purchasing offices (City of Tampa), state health and human services commissions (Texas HHS), and multistate cooperative purchasing alliances (Minnesota MMCAP), reflecting the breadth of state and local healthcare and emergency-response procurement.

Recent activity appears concentrated in Florida and Minnesota, with secondary activity in Texas and participation from Oregon through cooperative purchasing arrangements. Representative opportunities include Seminole County's IFB60459723LAS for 1,900 units of naloxone and 800 safe drug deactivation systems annually (due July 26, 2023), the City of Tampa's sealed-bid procurement (26P00145) for 169 line items of medical and first aid supplies for the Fire Department Rescue Division with a $700,000 estimated contract value and SLBE set-aside (due March 13, 2026), and MMCAP's multistate RFP (S1070000015802) for generic multi-source pharmaceuticals and OTC products to be distributed across state and local facilities effective July 1, 2026 (proposals due March 26, 2026). The code shows low relevance to actual state and local buying patterns; vendors should verify accurate code assignment before pursuing opportunities in this category.
