UNSPSC 51312404: Chlorothen

This classification denotes a histamine-1 receptor antagonist with the molecular formula C14H18ClN3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Y6068K376I, chemically known as 2-((5-chloro-2-thenyl)(2-(dimethylamino)ethyl)amino)pyridine but generally known as chlorothen, which bears US NIH Compound Identifier 8993. European Medicines Agency schedules chloropyrilene in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06195MIG. The term chloropyrilene is a U.S. FDA designation.

As of Q4 2014, CHLOROTHEN remains the US FDA Preferred Term for this commodity. Chlorothen bears US NLM identifiers UMLS ID C0164505 and NCI Concept Code C83621. SMILES: CN(C)CCN(CC1=CC=C(S1)Cl)C2=CC=CC=N2.

UNSPSC 51312404 Chlorothen, a Commodity code, does not align with the state and local procurement activity recently posted under this classification. The three most recent opportunities tagged to this code cover naloxone and drug deactivation systems procurement (Seminole County, Florida), a therapeutic pharmacy initiative request for information (Texas Health and Human Services Commission), and generic multi-source pharmaceuticals and over-the-counter products through a cooperative purchasing vehicle (Minnesota Multistate Cooperative Purchasing Alliance). None of these solicitations reference chlorothen or chemical disinfectants; the mismatch suggests either a tagging error in the source data or that state and local procurement offices are using this code to classify pharmaceutical and health-system supply acquisitions rather than the narrow chemical-sterilant product category the code nominally describes. Without recent opportunities genuinely soliciting chlorothen, the code shows little relevant procurement activity for vendors specializing in that product line.

The issuing bodies visible in these opportunities span state health and human services agencies, county health departments, and cooperative purchasing alliances serving multiple states and local jurisdictions. Seminole County, Florida posted an IFB (IFB60459723LAS) due July 26, 2023, for naloxone and drug deactivation systems with quarterly deliveries; the Texas HHS Commission issued an RFI (HHS0017013) on April 3, 2026, seeking vendor capabilities for direct-to-manufacturer prescription programs; and the Minnesota Department of Administration, on behalf of MMCAP, issued an RFP (S1070000015802) due March 26, 2026, for generic pharmaceuticals and OTC products distributed through authorized wholesalers. If this code is being used to flag pharmaceutical procurement broadly rather than chlorothen specifically, firms should verify the actual product scope before committing bid resources.
