UNSPSC 51191551: Mebutizide

This classification denotes a thiazide diuretic with the molecular formula C13H20ClN3O4S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 7738AS8324, chemically known as 6-chloro-3,4-dihydro-3-(1,2-dimethylbutyl)-2h-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide but generally known as mebutizide, which bears US NIH Compound Identifier 71652. European Medicines Agency schedules Mebutizide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08669MIG.

UNSPSC 51191551 Mebutizide is a Commodity code that in recent state and local solicitations encompasses chemical supply for water treatment and municipal utility operations, though the posted opportunities show a mismatch with the specific product name. The City of Meriden, Connecticut issued an IFB in July 2026 for sodium bisulfite chemical supply to its Water Pollution Control Facility, with bids due July 29, 2026—a clear municipal utility chemical procurement aligned with the code's nominal scope. A separate RFP from the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) posted in January 2026 for generic multi-source pharmaceuticals and OTC products appears miscoded under this UNSPSC category and does not represent relevant activity for mebutizide or water-treatment chemicals. The issuing bodies show a pattern of municipal utilities (public works departments overseeing water and wastewater facilities) and, less clearly in the available records, state cooperative purchasing alliances that aggregate demand across member agencies. Contractors pursuing work under this code should expect to provide commodity chemicals meeting specified quality standards and delivery schedules, with pricing evaluated on a unit-cost basis, and to carry substantial liability coverage (General Liability of $1 million to $2 million minimum, Auto Liability, and Umbrella coverage when required) with the issuing body named as Additional Insured.

Geographic activity is concentrated in the Northeast, with the City of Meriden, Connecticut representing a recent municipal utility purchase. The MMCAP opportunity, while multistate in scope, is not representative of mebutizide procurement. The Meriden IFB for sodium bisulfite, due July 29, 2026, stands as the only recent opportunity clearly aligned with the code's chemical-supply scope; it required performance bonds, labor and material payment bonds, and firm pricing for the contract term. No additional recent mebutizide-specific solicitations appear in the available state and local records.
