UNSPSC 51381601: Difenpiramide

This classification denotes a non-steroidal anti-inflammatory agent and acetamide with the molecular formula C19H16N2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Q6U5F6E1QL, chemically known as n-pyridin-2-yl(1,1-biphenyl)-4-acetamide but generally known as difenpiramide, which bears US NIH Compound Identifier 100472. World Health Organization schedules difenpiramide in its Anatomical Therapeutic Chemical (ATC) Classification. As of Q4 2014, DIFENPIRAMIDE remains the US FDA Preferred Term for this commodity.

SMILES: C1=CC=C(C=C1)C2=CC=C(C=C2)CC(=O)NC3=CC=CC=N3.

UNSPSC 51381601 Difenpiramide is a Commodity code that in recent state and local procurement activity covers chemical supplies for water treatment and pharmaceutical products distributed through cooperative purchasing agreements, though the code's nominal scope and actual solicitation activity show significant divergence. The City of Meriden is soliciting bids for sodium bisulfite chemical supply for its Water Pollution Control Facility under RFQ B027-15, with responses due July 29, 2026; separately, the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP on January 20, 2026 for generic multi-source pharmaceuticals and over-the-counter products with a March 26, 2026 response deadline. The Meriden solicitation involves unit-cost evaluation of chemical commodities for municipal water treatment operations, while the MMCAP procurement represents a cooperative purchasing vehicle serving multiple state and local government facilities across participating states, including Oregon, with pricing weighted at 75 percent and compliance with cGMP and DSCSA requirements. Both solicitations require comprehensive insurance coverage; the Meriden contract mandates General Liability of $1,000,000 to $2,000,000, while MMCAP requires $5,000,000 per occurrence for commercial general liability plus additional network security and professional liability coverage.

The code shows limited recent activity concentrated in the Northeast and Upper Midwest, with the City of Meriden (Connecticut) and MMCAP (Minnesota-administered cooperative) representing the two posted opportunities in the dataset. The Meriden IFB reflects municipal utility procurement for chemical inputs, while MMCAP's RFP model demonstrates state and local demand through cooperative purchasing structures serving multiple jurisdictions simultaneously. No other geographic clustering or repeat issuing bodies appear in the recent opportunities block. The mismatch between the code's nominal scope (difenpiramide, an agricultural fungicide) and the actual solicitations for water treatment chemicals and pharmaceuticals suggests the code may carry inaccurate tagging in state and local procurement systems, limiting its reliability as a forward indicator of future opportunities in this specific commodity category.
