UNSPSC 51131633: Diphacinone or diphenadione

This classification denotes an anticoagulant agent with the molecular formula C23H16O3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 54CA01C6JX, chemically known as 1,3-indandione, 2-(diphenylacetyl)- (8ci) but generally known as diphacinone, which bears US NIH Compound Identifier 6719. European Medicines Agency schedules Diphenadione in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07209MIG. The term DIPHACINONE is an International Non-Proprietary Name.

World Health Organization schedules diphacinone in its Anatomical Therapeutic Chemical (ATC) Classification. Diphacinone or diphenadione bears US NLM identifiers UMLS ID C0058366 and NCI Concept Code C75156. SMILES: C1=CC=C(C=C1)C(C2=CC=CC=C2)C(=O)C3C(=O)C4=CC=CC=C4C3=O.

UNSPSC 51131633 Diphacinone or diphenadione is a Commodity code that nominally covers rodent and pest control chemicals, but recent state and local procurement activity shows little alignment with this scope. Sourcewell, a Minnesota cooperative purchasing vehicle, issued RFP #061626 in May 2026 for Law Enforcement Equipment on behalf of participating counties and public entities across multiple states, with a June 16, 2026 response deadline. The solicitation does not specify pest control or chemical procurement and instead addresses law enforcement equipment broadly, suggesting that either the code was misapplied to the opportunity or the category sees minimal recent activity in state and local government procurement under its intended commodity definition.

Geographic activity remains unclear from available records. Sourcewell's RFP encompasses Franklin, Grant, Grays Harbor, Chelan, and Yakima counties in Washington, plus numerous other jurisdictions in the United States and Canada, but this is a cooperative purchasing framework rather than a direct signal of diphacinone or diphenadione procurement demand. No other recent state or local opportunities under this Commodity code are documented, indicating either sparse actual demand for this specific pesticide in the public sector or consistent misclassification in procurement systems. Firms targeting this code should verify whether state and local health departments, vector control districts, or parks departments are actively sourcing these chemicals under different UNSPSC codes or through state chemical bid schedules before committing pursuit resources.
