UNSPSC 51452002: Arsenamide or thiacetarsamide

This classification denotes an antihelminthic agent with the molecular formula C11H12AsNO5S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier VMF4ELY9TZ, chemically known as acetic acid, mercapto-, p-carbamoyldithiobenzenearsonite (2:1) but generally known as arsenamide, which bears US NIH Compound Identifier 10749. Arsenamide or thiacetarsamide bears US NLM identifiers UMLS ID C0003815 and NCI Concept Code C66595. SMILES: [AS](SCC(=O)O)(SCC(=O)O)C1CCC(CC1)C(=O)N.

UNSPSC 51452002 Arsenamide or thiacetarsamide, a Commodity code, shows minimal alignment with recent state and local procurement activity. The code nominally describes a veterinary parasiticide, but the four most recent opportunities posted under or near this code span naloxone procurement, direct-to-manufacturer prescription programs, fire department medical supplies, and generic pharmaceutical distribution — none of which involve arsenamide or thiacetarsamide products. The code's narrow pharmaceutical scope appears to reflect a legacy taxonomy classification that does not match contemporary state and local buying patterns in this therapeutic area.

Recent activity under this code includes an IFB from Seminole County, Florida (IFB60459723LAS, due July 26, 2023) for naloxone and drug deactivation systems; a Request for Information from the Texas Health and Human Services Commission (HHS0017013, posted April 3, 2026) on direct-to-manufacturer prescription fulfillment; an ITB from the City of Tampa (26P00145, due March 13, 2026) for medical and first aid supplies supporting the Tampa Fire Department Rescue Division with an estimated contract value of $700,000; and a cooperative purchasing RFP from the Minnesota Multistate Cooperative Purchasing Alliance (S1070000015802, due March 26, 2026) for generic multi-source pharmaceuticals and OTC products distributed across participating state and local facilities including Oregon. The Tampa procurement is designated as a sheltered market for certified Small Local Business Enterprises with a 5% bid discount capped at $10,000. The geographic spread reflects activity in Florida, Texas, Minnesota, and Oregon, but the issuing bodies and scope of work diverge substantially from the code's nominal descriptor. State and local procurement offices appear to be tagging pharmaceutical and medical-supply solicitations under this code without regard to arsenamide or thiacetarsamide specificity, suggesting either a classification error in the source data or disuse of the code for its intended purpose.
