UNSPSC 51151634: Diphemanil

This classification denotes an antimuscarinic agent with the molecular formula C20H24N, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Q26TX1UD0W, chemically known as 4-(diphenylmethylene)-1,1-dimethylpiperidinium methylsulfate but generally known as diphemanil, which bears US NIH Compound Identifier 6126. World Health Organization schedules diphemanil in its Anatomical Therapeutic Chemical (ATC) Classification. DIPHEMANIL is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix.

As of Q4 2014, DIPHEMANIL remains the US FDA Preferred Term for this commodity. Diphemanil bears US NLM identifiers UMLS ID C0301371 and NCI Concept Code C78071. SMILES: C[N+]1(CCC(=C(C2=CC=CC=C2)C3=CC=CC=C3)CC1)C.COS(=O)(=O)[O-]..

UNSPSC 51151634 Diphemanil (Commodity) does not appear in the recent state and local procurement activity the source provides. The two opportunities tagged with this code—Seminole County's solicitation for Naloxone and drug deactivation systems, and the Texas Health and Human Services Commission's RFI on direct-to-manufacturer prescription programs—address pharmaceutical procurement and pharmacy benefit management, but neither involves diphemanil, an anticholinergic medication used in specific clinical contexts. The code's nominal scope and the actual work being solicited diverge substantially, signaling either miscoding in the underlying source data or absence of current state and local contracting activity in this specific pharmaceutical commodity.

The Seminole County opportunity (IFB60459723LAS, response deadline July 26, 2023) sought Naloxone and safe drug deactivation systems on a competitive bid basis with quarterly deliveries to the county's community health building, while the Texas HHS RFI (HHS0017013, posted April 3, 2026) gathered market intelligence on direct-to-manufacturer prescription programs without identifying specific pharmaceutical products. Neither represents purchasing activity under the diphemanil commodity code as nominally defined. A business development professional evaluating this code should treat it as currently inactive for state and local procurement and verify the actual UNSPSC coding used by target jurisdictions before committing resources to pursuit.
