UNSPSC 51171628: Potassium phosphate

This classification denotes an electrolyte replacement agent with the molecular formula 2K.HO4P, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier CI71S98N1Z, chemically known as potassium phosphate, monobasic (jan/nf) but generally known as potassium phosphate, which bears US NIH Compound Identifier 24506. European Medicines Agency schedules Potassium phosphate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB21612.

Potassium phosphate bears US NLM identifiers UMLS ID C0071778 and NCI Concept Code C29373. SMILES: OP(=O)(O)[O-].[K+].

UNSPSC 51171628 Potassium phosphate is a Commodity code that describes specialized chemical inputs for municipal and institutional operations, though recent state and local activity shows limited direct procurement of potassium phosphate itself. Instead, the opportunities tagged under this code reflect a broader pattern of chemical and pharmaceutical supply across water treatment, wastewater management, and correctional healthcare. State and local issuing bodies soliciting under related chemistry codes include municipal water and wastewater agencies (such as the City of Meriden, Connecticut), county environmental infrastructure departments (Broward County, Florida), and state correctional healthcare systems (Washington State Department of Corrections). The work encompasses on-demand chemical supply for compliance-driven treatment processes, emergency pharmaceutical provisioning to distributed facilities, and specialized industrial chemicals for permit-mandated operations.

Activity in this code family shows geographic spread across Florida, Connecticut, and Washington State. The City of Meriden issued an IFB for sodium bisulfite supply (solicitation B027-15, due July 29, 2026) for its Water Pollution Control Facility, establishing the pattern of unit-cost chemical procurement for municipal treatment. Broward County, Florida posted a Request for Information (BLD6232026F23, due September 29, 2026) on DeZurik/APCO valve parts and repair services for wastewater facilities, signaling a related but tangential scope involving process-control equipment rather than consumable chemistry. The Washington State Department of Corrections issued an RFQ for parenteral products and services (RFQQK13020, due October 7, 2026) across eight correctional facilities, showing acute-care pharmaceutical supply with strict delivery windows (24 hours for parenteral nutrition, 8 hours for other products) and multi-region award strategy. Set-aside participation goals in the DOC solicitation target small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%).
