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 with minimal recent state and local procurement activity directly aligned to its nominal scope. The three most recent opportunities tagged under this code involve water treatment chemicals (sodium bisulfite for municipal wastewater control), parenteral medical products and services (intravenous solutions and nutrition preparations for correctional healthcare), and industrial valve parts and repair services (DeZurik/APCO valves for wastewater facilities). None of these solicitations target difenpiramide, a specific agrochemical herbicide. The mismatch suggests either misclassification at posting or that state and local procurement offices are using this code as a catch-all for specialized chemical and medical commodities without precision-level category alignment.

Recent activity spans three jurisdictions: Broward County, Florida (valve parts and repair services RFI posted September 18, 2026, due September 29, 2026); the Washington State Department of Corrections (parenteral products and services RFQQ posted September 8, 2026, due October 7, 2026, with pre-bid conference September 23, 2026); and the City of Meriden, Connecticut (sodium bisulfite chemical supply IFB posted August 14, 2026, due July 29, 2026). The Washington DOC opportunity spans eight correctional facilities across three regions and anticipates selecting multiple contractors with firm pricing through June 30, 2030. Set-asides include small business (25%), minority-owned (10%), women-owned (6%), and veteran-owned (5%) targets with Washington State certification required. Given the code's current activity pattern, suppliers of specialized chemicals, medical products, and industrial equipment components should monitor for misclassified opportunities but should not rely on this code alone for targeted business development.
