UNSPSC 51191534: Besulpamide

This classification denotes a diuretic with the molecular formula C15H16ClN3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 048UJ2MM65, chemically known as 1-((4-chloro-3-sulfamoylbenzoyl)amino)-2,4,6-trimethylpyridinium hydroxide, inner salt but generally known as besulpamide, which bears US NIH Compound Identifier 9571085. European Medicines Agency schedules Besulpamide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05789MIG.

UNSPSC 51191534 Besulpamide is a Commodity code covering chemical compounds used in municipal water treatment and industrial processes, though recent state and local solicitations show minimal activity specific to besulpamide itself. The City of Meriden's July 2026 IFB for sodium bisulfite (B02715, due July 29, 2026) exemplifies the water pollution control application — the city procures chemical supply for its Water Pollution Control Facility under firm unit-cost pricing. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP for generic multi-source pharmaceuticals and OTC products (S1070000015802, due March 26, 2026) appears to have been incorrectly coded to this commodity, as it addresses pharmaceutical manufacturing and distribution rather than industrial chemical compounds. Municipal water and wastewater treatment authorities represent the primary issuing-body type for genuine besulpamide or related-compound procurement; state cooperative purchasing vehicles occasionally tag chemical-supply contracts to this code, though typically for unrelated pharmaceutical or OTC products.

Activity under this code is concentrated in the Northeast and Upper Midwest. The City of Meriden, Connecticut, issued the only clearly relevant recent solicitation for water-treatment chemical supply. The MMCAP opportunity (Minnesota Department of Administration administering on behalf of multiple state and local participants across Minnesota and Oregon) shows geographic diversity but represents pharmaceutical procurement misclassified to this code. Vendors pursuing municipal water-treatment chemical supply should monitor Connecticut and neighboring state procurement portals directly rather than relying on this code classification alone; the code's sparse recent activity suggests that state and local agencies often tag water-treatment chemicals under broader chemical-supply codes or general commodities rather than commodity-specific classifications.
