UNSPSC 51332847: Duoperone fumarate

This classification denotes a phenothiazine and antipsychotic agent C28H26F4N2OS.C4H4O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier G7MM186D7U, chemically known as methanone, (4-fluorophenyl)(1-(3-(2-(trifluoromethyl)-10h-phenothiazin-10-yl)propyl)-4-piperidinyl)-, (e)-2-butenedioate (1:1), but more generally known as duoperone fumarate, which bears US NIH Compound Identifier 43876. Most nations, for tariff and trade purposes, schedule duoperone fumarate under HS 29343090 and SITC 51578.

As of Q4 2014, DUOPERONE FUMARATE remains US FDA's Preferred Term for this commodity. Duoperone fumarate bears US NLM identifiers UMLS ID C0115127 and NCI Concept Code C74170. SMILES: C1CCC2C(C1)N(C3CC(CCC3S2)C(F)(F)F)CCCN4CCC(CC4)C(=O)C5CCC(CC5)F.C(=C/C(=O)O)\C(=O)O.

UNSPSC 51332847 Duoperone fumarate is a Commodity code that does not match the work actually being solicited under it in recent state and local procurement activity. The three recent opportunities posted under this code involve naloxone procurement, direct-to-manufacturer prescription programs, and generic multi-source pharmaceuticals and OTC products — none of which are duoperone fumarate or pharmaceutical intermediates. The code shows little relevant recent activity aligned with its nominal scope.

The mismatch between the code designation and the actual procurement work reflects a tagging inconsistency in the source data rather than an active buying market for duoperone fumarate at the state and local level. Seminole County, Florida issued an IFB for naloxone and drug deactivation systems in June 2026; the Texas Health and Human Services Commission posted an RFI on direct-to-manufacturer prescription fulfillment in April 2026; and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) solicited generic pharmaceuticals and OTC products through an RFP due March 26, 2026. None of these solicitations target duoperone fumarate as a procurement item. Business development professionals should verify whether duoperone fumarate has actionable recent state and local procurement volume before allocating pursuit resources to this code.
