This classification denotes drugs or other substances that raise blood PH levels.

UNSPSC 51191700 Alkalinizing agents is a Class code covering chemical products used in water treatment and related municipal and healthcare operations. State and local governments procure under this code to source chemicals for wastewater treatment, water pollution control, and healthcare delivery to correctional facilities. The issuing bodies span municipal water departments, county utilities, and state corrections agencies. Recent solicitations show demand for specialized chemicals including sodium bisulfite for pollution control facilities, valve maintenance and repair services integrated with wastewater treatment compliance systems, and parenteral nutrition and intravenous solutions for incarcerated populations requiring medical delivery within strict time windows.

Recent activity appears in Florida, Connecticut, and Washington. The City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical supply (solicitation B027-15, due July 29, 2026) for its Water Pollution Control Facility. Broward County, Florida posted a Request for Information on DeZurik/APCO valves, parts, and repair services (solicitation BLD6232026F23, due September 29, 2026) to evaluate sole-source vendor viability for wastewater treatment compliance. The Washington State Department of Corrections issued an RFQQ for parenteral products, services, and equipment across eight correctional facilities in three regions (solicitation RFQQK13020, due October 7, 2026 at 4:00 PM PST) with parenteral nutrition bags requiring delivery within 24 hours of order and other parenteral products within 8 hours, with DOC retaining discretion to award up to three contractors per region under a contract term running November 26, 2026 through June 30, 2030. Washington State encourages participation from small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%).
