UNSPSC 51131606: Sodium apolate

This classification denotes an anticoagulant agent and a alkyl sulfonate, phosphogluconate dehydrogenase antagonists and inhibitor, polyvinyl, polyethylene, and sulfonic acid with the molecular formula C2H3NaO3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 9461405D9F, chemically known as sodium;ethenesulfonate but generally known as sodium apolate, which bears US NIH Compound Identifier 3270262.

European Medicines Agency schedules Sodium Apolate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05545MIG. The term SODIUM APOLATE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Vol 20 1966, List 6). Most nations schedule sodium apolate under HS 39019090 and SITC 57190. SMILES: C=CS(=O)(=O)[O-].[Na+]

UNSPSC 51131606 Sodium apolate, a Commodity code, nominally covers chemical sodium compounds used in pharmaceutical and industrial applications, but the recent state and local procurement activity under this code does not reflect that scope. Sourcewell, a Minnesota local government cooperative, posted RFP #061626 in May 2026 seeking Law Enforcement Equipment on behalf of its Participating Entities across multiple jurisdictions including Franklin, Grant, Grays Harbor, Chelan, and Yakima counties in Washington and public entities throughout the United States and Canada. The solicitation targets thousands of governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, tribal governments, and other public entities through a cooperative purchasing framework. The mismatch between the code's chemical-products designation and the law-enforcement-equipment procurement suggests either a classification error in how the opportunity was tagged or that the code shows little relevant state and local activity aligned with its nominal scope.

The single recent opportunity identified under this code is Sourcewell's RFP #061626, due June 16, 2026 at 3:30 p.m. Central Time, submitted through the Sourcewell Procurement Portal. The cooperative purchasing structure extends across Washington state and multiple additional jurisdictions, with no specific set-aside designations, incumbent vendors, or award values disclosed in available documentation. Questions are directed to Mari Vielma at rfp@sourcewell-mn.gov or 888-894-1930. The code does not support sufficient recent, on-scope activity to characterize meaningful geographic spread or issuing-body concentration in state and local procurement of sodium apolate products.
