UNSPSC 51171958: Propinetidine

This classification denotes a histamine-2 receptor antagonist, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 70QV580PA4. European Medicines Agency schedules Propinetidine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10108MIG. Propinetidine generally arises in the molecular formula C19H25NO2. The term PROPINETIDINE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 19 1975, list 5.) Most nations schedule propinetidine under HS 29333999 and SITC 51574.

As of Q4 2014, PROPINETIDINE remains the US FDA Preferred Term for this commodity. Propinetidine bears US NLM identifiers UMLS ID C1882491 and NCI Concept Code C66484. SMILES: O(C1(CCN(CC1)CCC1CCCCC1)CC#C)C(=O)CC.

UNSPSC 51171958 Propinetidine, a Commodity code, does not reflect what state and local governments are actually buying under this designation. Recent contract opportunities tagged to this code span offender drug-testing services, direct-to-manufacturer pharmaceutical procurement strategy, and generic pharmaceutical distribution through cooperative purchasing — none of which involve propinetidine as a product. The code shows a mismatch between its nominal scope and the work solicited, making it a poor classifier for this procurement activity.

The most substantial recent opportunity is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services, due July 23, 2026, with an estimated contract value of $600,000 over two years with optional renewals through five years total. The Texas Health and Human Services Commission issued an exploratory RFI in April 2026 on direct-to-manufacturer prescription programs but has not yet posted a formal solicitation. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by Minnesota's Department of Administration, posted an RFP on January 20, 2026 (due March 26, 2026) to establish multiple contracts for generic pharmaceuticals and OTC products across participating state and local government facilities, including Oregon, with contract terms effective July 1, 2026. The Collin County and MMCAP opportunities represent genuine procurement activity; the HHS RFI is an information-gathering phase preceding future formal solicitations. Given the code's structural mismatch with the actual work being bought, practitioners should verify the correct UNSPSC classification for pharmaceutical procurement, drug-testing services, or related scope before pursuing opportunities initially tagged to this code.
