UNSPSC 51191554: Isosorbide dinitrate

This classification denotes a vasodilating agent with the molecular formula C6H8N2O8, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier IA7306519N, chemically known as 1,4:3,6-dianhydrosorbitol 2, 5-dinitrate but generally known as isosorbide dinitrate, which bears US NIH Compound Identifier 3780. European Medicines Agency schedules Isosorbide dinitrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08335MIG.

UNSPSC 51191554 Isosorbide dinitrate is a Commodity code that nominally describes pharmaceutical preparations, but recent state and local opportunities posted under this code show a significant taxonomy mismatch — the three most recent solicitations involve industrial valves and repair services for wastewater treatment, parenteral nutrition and intravenous solutions for correctional healthcare, and sodium bisulfite chemical supply for water treatment, none of which are isosorbide dinitrate or related cardiac medications. The code appears to be capturing a diverse range of medical, pharmaceutical, and chemical products and services across multiple operational contexts rather than the specific nitrate preparation its name suggests. Issuing bodies include state departments (Washington State Department of Corrections), county governments (Broward County, Florida), and municipalities (City of Meriden, Connecticut), indicating fragmented procurement across different governance tiers and functional areas — healthcare delivery, environmental compliance, and infrastructure maintenance.

The most recent activity spans Florida, Washington, and Connecticut. The Washington State Department of Corrections RFQ for parenteral products, services, and equipment (RFQQK13020, due October 7, 2026) seeks parenteral nutrition and IV solutions delivered to eight correctional facilities across three regions, with pre-bid conference on September 23, 2026, aspirational set-aside goals for small business (25%), minority-owned (10%), women-owned (6%), and veteran-owned (5%) providers, and an initial contract term through June 30, 2030 with fixed pricing for the first two years. Broward County, Florida issued a Request for Information on DeZurik/APCO valves, parts, and repair services (BLD6232026F23, due September 29, 2026) to identify alternative suppliers to the current exclusive provider before potential sole-source designation, requiring SCADA-compatible equipment for wastewater compliance. The City of Meriden, Connecticut solicited bids for sodium bisulfite chemical supply (B027-15, due July 29, 2026) for the Water Pollution Control Facility. The code shows no cohesive pharmaceutical focus and appears misaligned with its stated commodity definition.
