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 is a Commodity code that shows minimal alignment with recent state and local procurement activity. The single recent opportunity tagged to this code—Sourcewell RFP #061626, posted May 12, 2026 with a June 16, 2026 response deadline—solicits law enforcement equipment broadly, not sodium apolate or related chemical compounds. Sourcewell, a Minnesota local government unit and service cooperative, is issuing the RFP on behalf of participating entities including Franklin County, Grant County, Grays Harbor County, Chelan County, and Yakima County in Washington state, alongside numerous other jurisdictions and public entities throughout the United States and Canada. The cooperative purchasing vehicle is structured to establish a contracting solution available to governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, tribal governments, and other public entities. No specific set-aside designations, incumbent vendors, or award values are disclosed in available documentation.

The geographic scope spans Washington state and beyond through the Sourcewell cooperative framework, but the actual procurement—law enforcement equipment—does not correspond to the sodium apolate commodity classification. No other recent state and local solicitations under this code appear in the available data. The mismatch between the code assignment and the work being solicited suggests either a tagging error or minimal genuine procurement activity under UNSPSC 51131606 at the state and local level. Business development professionals should verify whether sodium apolate represents an active procurement category for their target jurisdictions before committing resources to monitor this code.
