UNSPSC 51191555: Isosorbide mononitrate

This classification denotes a vasodilating agent with the molecular formula C6H9NO6, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier LX1OH63030, chemically known as 1,4:3,6-dianhydro-d-glucitol 5-nitrate but generally known as isosorbide mononitrate, which bears US NIH Compound Identifier 27661. European Medicines Agency schedules Isosorbide mononitrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08336MIG.

UNSPSC 51191555 Isosorbide mononitrate is a Commodity code that covers pharmaceutical and chemical products for state and local government use, though recent solicitations posted under this code show minimal alignment with its nominal scope. The City of Meriden's July 2026 IFB for sodium bisulfite chemical supply for municipal water treatment operations and the Minnesota Multistate Cooperative Purchasing Alliance's January 2026 RFP for generic multi-source pharmaceuticals and over-the-counter products represent the recent activity tagged to this code. State and local issuing bodies using this code span municipal water departments, state procurement offices administering cooperative purchasing vehicles, and broader health and human services procurement. The Minnesota Department of Administration's Office of State Procurement administers MMCAP on behalf of participating state and local government facilities across multiple states including Oregon.

Geographic activity centers on Connecticut and Minnesota based on the recent solicitations. The City of Meriden's sodium bisulfite procurement closed July 29, 2026; bidders must carry General Liability of $1,000,000 to $2,000,000 and Workers' Compensation at Connecticut statutory limits, with performance and payment bonds required. The MMCAP RFP, with a March 26, 2026 response date and a July 1, 2026 contract effective date, requires vendors to supply through three authorized wholesalers and maintain commercial general liability of $5,000,000 per occurrence, network security and privacy liability of $2,000,000, and professional liability of $2,000,000. Vendors must certify cGMP and Drug Supply Chain Security Act compliance. The mismatch between the code's stated scope (isosorbide mononitrate, a cardiac medication) and the actual commodities solicited (sodium bisulfite and broad-based generic pharmaceuticals) suggests this code sees limited relevant activity for firms targeting cardiac-specific pharmaceutical procurement.
