UNSPSC 51191501 Chlorothiazide is a Commodity code that in practice spans a much broader range of pharmaceutical and chemical products than its nominal name suggests. Recent state and local solicitations under this code include parenteral nutrition and intravenous solutions for correctional healthcare, industrial chemicals such as sodium bisulfite for water treatment, and specialized valve components for wastewater systems. The issuing bodies are primarily state corrections and health agencies alongside municipal utilities and county infrastructure departments. These jurisdictions procure both critical care pharmaceuticals and process chemicals under this single commodity classification, reflecting how state and local taxonomy sometimes groups functionally distinct products under a single code based on procurement classification logic rather than industry function.

Washington State Department of Corrections is the most active recent buyer, soliciting parenteral products, services, and equipment (including TPN, PPN, and IV solutions) for eight correctional facilities across the state with an RFQ due October 7, 2026, and a pre-bid conference on September 23, 2026; the initial contract runs through June 30, 2030 with DOC anticipating multiple award winners and targeting set-asides for small, minority-owned, women-owned, and veteran-owned businesses. The City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical supply to its Water Pollution Control Facility with a due date of July 29, 2026. Broward County, Florida posted an RFI on September 18, 2026 (due September 29) regarding DeZurik/APCO valves and repair services for wastewater treatment systems, currently seeking to determine whether sole-source designation of Controls Specialties, Inc. is necessary. Recent activity clusters in Florida, Washington, and Connecticut, with the largest current opportunity in the Pacific Northwest tied to correctional healthcare supply.
