UNSPSC 51131605: Sodium citrate

This classification denotes an electrolyte replacement agent and anticoagulant agent, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 1Q73Q2JULR. European Medicines Agency schedules Sodium citrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12582MIG. Sodium citrate generally arises in the molecular formula C6H5NA3O7. The term 'sodium citrate' is a U.S. Pharmacopeial Convention designation. As of Q4 2014, SODIUM CITRATE remains the US FDA Preferred Term for this commodity.

Sodium citrate bears US NLM identifiers UMLS ID C0142825 and NCI Concept Code C62075. SMILES: C(C(=O)[O-])C(CC(=O)[O-])(C(=O)[O-])O.[Na+].[Na+].[Na+].

UNSPSC 51131605 Sodium citrate is a Commodity code that in state and local procurement activity appears primarily in law enforcement and public safety supply contracts. The recent opportunity block shows minimal direct alignment between the code's nominal scope—a chemical compound used in medical and laboratory settings—and the actual solicitations being posted under it. Sourcewell, the Minnesota-based cooperative purchasing vehicle, issued RFP #061626 in May 2026 tagged to this code, but the solicitation itself targets law enforcement equipment broadly across multiple jurisdictions and public entity types, not sodium citrate specifically. This mismatch suggests either misclassification in the posting system or use of the code as a catch-all within a broader equipment family. State and local governments purchasing under this code appear to include county governments (Franklin, Grant, Grays Harbor, Chelan, and Yakima counties in Washington), school districts, transit and public authorities, and nonprofit organizations operating through cooperative purchasing arrangements.

The geographic spread of activity centers on Washington state and Minnesota, with the Sourcewell vehicle extending availability nationally and into Canada. The single recent opportunity of note is Sourcewell's RFP #061626 for Law Enforcement Equipment, posted May 12, 2026 with a response deadline of June 16, 2026 at 3:30 p.m. Central Time, submitted through the Sourcewell Procurement Portal. The solicitation does not disclose award value, set-aside designations, or incumbent vendors, and establishes a cooperative contracting vehicle available to thousands of governmental agencies rather than a single jurisdiction purchase. The code shows limited recent activity aligned with its chemical-compound definition in standard state and local procurement.
