UNSPSC 51131662: Parnaparin

This classification denotes a low molecular weight heparin with the molecular formula (C14H18NO11)n.2(C12H16NO13S)n.3HO3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier M316WT19D8, chemically known as (4S,6R)-6-[(2R,4R)-4,6-dihydroxy-5-(sulfonatoamino)-2-(sulfonatooxymethyl)oxan-3-yl]oxy-3,4-dihydroxy-5-sulfonatooxyoxane-2-carboxylate, but generally known as Parnaparin. European Medicines Agency schedules Parnaparin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB22270.

The term Parnaparin is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 5, No. 3 1991, List 31). As of Q4 2014, PARNAPARIN remains the US FDA Preferred Term for this commodity. SMILES: C(C1C(C(C(C(O1)O)NS(=O)(=O)[O-])O)OC2C(C(C(C(O2)C(=O)[O-])O)O)OS(=O)(=O)[O-])OS(=O)(=O)[O-].

UNSPSC 51131662 Parnaparin is a Commodity code that designates a specific anticoagulant pharmaceutical product. State and local procurement activity under this code shows minimal recent solicitation. The single recent opportunity tagged to this code—Sourcewell RFP #061626, posted May 12, 2026 with a response deadline of June 16, 2026—is titled "Law Enforcement Equipment - SW" and addresses procurement of law enforcement equipment for cooperative purchasing across multiple jurisdictions, not pharmaceutical supplies or anticoagulants. This mismatch indicates either a data-tagging error or a divergence between the code assignment and the actual goods being solicited, and suggests the code carries little operational relevance in current state and local procurement activity.

The single RFP represents a Sourcewell cooperative purchasing vehicle on behalf of participating entities in Washington state, including Franklin, Grant, Grays Harbor, Chelan, and Yakima counties, structured to serve thousands of governmental agencies, school districts, tribal governments, and nonprofit organizations across the United States and Canada. No specific dollar values, award criteria, set-aside designations, or incumbent vendor names are disclosed in available solicitation materials. Prospective vendors access all documentation through the Sourcewell Procurement Portal at https://proportal.sourcewell-mn.gov and submit questions to Mari Vielma (rfp@sourcewell-mn.gov or 888-894-1930). Given the subject matter of the single recent opportunity does not align with the code's pharmaceutical scope, this code does not appear to reflect genuine procurement activity for parnaparin or related anticoagulant products at the state and local level.
