UNSPSC 51191805: Potassium citrate

This classification denotes an electrolyte replacement agent with the molecular formula C6H5O7.3K.H2O, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier EE90ONI6FF, chemically known as 1,2,3-propanetricarboxylic acid, 2-hydroxy-, tripotassium salt but more generally known as potassium citrate, which bears U.S. NIH Compound Identifier 13344. European Medicines Agency schedules Potassium citrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14973MIG.

World Health Organization schedules potassium citrate in its Anatomical Therapeutic Chemical (ATC) Classification and its WHO-DD or Drug Dictionary.

UNSPSC 51191805 Potassium citrate is a Commodity code that encompasses specialty chemicals used across diverse state and local operations. Recent solicitation activity reveals that state and local governments are procuring potassium citrate and related specialty chemical compounds for water treatment, wastewater management, and healthcare delivery — though the recent opportunities block shows only tangential alignment with the code's nominal scope. The issuing bodies reflect a broad mix of jurisdictions: municipal water and wastewater utilities (the City of Meriden, Connecticut), county-level infrastructure operators (Broward County, Florida), and state correctional healthcare systems (Washington State Department of Corrections). Scope of work varies sharply by customer type: municipal water treatment facilities specify potassium citrate and related compounds for chemical adjustment and dechlorination; wastewater systems focus on valve components and control systems rather than chemical commodities; and correctional healthcare systems procure parenteral nutrition solutions and intravenous products for incarcerated populations. The code shows limited direct activity for potassium citrate procurement — the recent opportunities named sodium bisulfite for water treatment (Meriden), DeZurik/APCO valves for wastewater (Broward County), and parenteral nutrition solutions for corrections (Washington State Department of Corrections), none of which align squarely with the potassium citrate commodity designation.

Activity is concentrated in Florida, Connecticut, and Washington State. Representative recent solicitations include the City of Meriden's IFB for sodium bisulfite chemical supply to its Water Pollution Control Facility (due July 29, 2026), Broward County's RFI for DeZurik/APCO valves and repair services to determine sole-source justification (due September 29, 2026), and the Washington State Department of Corrections' RFQQ for parenteral products and services to eight correctional facilities across three regions (due October 7, 2026 at 4:00 PM PST, with a pre-bid conference on September 23, 2026). The DOC opportunity explicitly encourages participation from small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%), with aspirational small and diverse business goals of 5%. Contracts anticipate multiple awards per region and fixed pricing through the initial two-year term. The code shows minimal recent relevant activity for potassium citrate specifically; procurement professionals should verify whether state and local issuing bodies classify potassium citrate purchases under this code in practice or rely on alternative procurement classifications.
