UNSPSC 51191574 Chlorothiazide sodium is a Commodity code that state and local governments use to classify pharmaceutical and chemical products for healthcare and water-treatment applications. Recent solicitations under this code span parenteral pharmaceutical products—intravenous solutions, nutritional preparations, and controlled substances for correctional healthcare—and industrial chemicals such as sodium bisulfite for water-pollution control. State and local issuing bodies include corrections departments, municipal water utilities, and county purchasing offices. The Washington State Department of Corrections and the City of Meriden are recent active buyers, with the DOC's multi-facility parenteral-products contract particularly representative of the scope: the solicitation requires documented capability to prepare and deliver IV solutions and parenteral nutrition bags within tight delivery windows (24 hours for nutrition bags, 8 hours for other products) to multiple correctional facilities across three regions. Broward County, Florida issued an RFI on DeZurik/APCO valves and wastewater-system repair services, which falls outside the nominal pharmaceutical and chemical scope of this Commodity code and does not represent typical activity under 51191574.

Activity under this code concentrates in Washington State and Florida, with the most recent significant opportunity in Washington. The Washington State Department of Corrections RFQ (RFQQK13020), due October 7, 2026, solicits parenteral products, services, and equipment for eight facilities with responses due by 4:00 PM PST, offering set-asides for small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%); DOC anticipates awarding up to three contractors per region with an initial term running November 26, 2026 through June 30, 2030 and fixed pricing for the first two years. The City of Meriden's IFB (B027-15) for sodium bisulfite chemical supply, due July 29, 2026, represents municipal water-treatment procurement under the code. The City of Meriden requires a performance bond and labor and material payment bond, with contractor insurance including $1,000,000 to $2,000,000 General Liability coverage. A pre-bid conference is scheduled for September 23, 2026 for the DOC solicitation, with questions due September 22, 2026.
