UNSPSC 51191915: Calcium gluconate

This classification denotes an electrolyte replacement agent with the molecular formula 2C6H11O7.Ca, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier SQE6VB453K, chemically known as gluconic acid, calcium salt but generally known as calcium gluconate, which bears US NIH Compound Identifier 9290. European Medicines Agency schedules Calcium gluconate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13176MIG.

World Health Organization schedules calcium gluconate in its Anatomical Therapeutic Chemical (ATC) Classification. As of Q4 2014, CALCIUM GLUCONATE remains the US FDA Preferred Term for this commodity. Calcium gluconate bears US NLM identifiers UMLS ID C0006699 and NCI Concept Code C336. SMILES: C(C(C(C(C(C(=O)[O-])O)O)O)O)O.C(C(C(C(C(C(=O)[O-])O)O)O)O)O.[CA+2].

UNSPSC 51191915 Calcium gluconate is a Commodity code that in practice covers specialized intravenous and parenteral pharmaceutical products, chemical treatment supplies, and related services for state and local healthcare, correctional, and municipal water treatment operations. State and local governments buy calcium gluconate and functionally similar parenteral nutrition solutions, IV products, chemical additives for water treatment, and associated delivery and monitoring services under this code. Issuing bodies span state corrections departments, municipal water utilities, county wastewater treatment authorities, and healthcare facilities operated by state and local governments. Recent opportunities show demand from specialized high-compliance environments—correctional healthcare systems requiring controlled-substance parenteral products with rapid delivery turnaround, and municipal water and wastewater treatment plants requiring chemical additives for permit compliance.

Activity in the source appears concentrated in the Pacific Northwest and Florida, with recent solicitations from the Washington State Department of Corrections (RFQ for parenteral products, services, and equipment with responses due October 7, 2026, to supply eight correctional facilities across three regions), the City of Meriden, Connecticut (IFB for sodium bisulfite chemical supply for the Water Pollution Control Facility, bid due July 29, 2026), and Broward County, Florida (RFI on DeZurik/APCO valves and repair services posted September 18, 2026, due September 29, 2026, to support wastewater treatment compliance). The Washington Department of Corrections opportunity anticipates multiple awards and includes set-aside incentives for small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%), with a subcontractor inclusion plan required. Delivery performance is critical—the DOC contract mandates parenteral nutrition bag delivery within 24 hours of order and other parenteral products within 8 hours for first supply.
