UNSPSC 51172331: Ethylenediaminetetraacetic acid (EDTA)

This classification denotes a chelating agent and anticoagulant agent with the molecular formula C10H16N2O8, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier 9G34HU7RV0. The European Medicines Agency schedules edta in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB16095MIG. The term EDETIC ACID is an International Non-Proprietary Name or INN (see World Health Organization INN reference publication, volume 13, no. 12, 1959, list 3. ). SMILES: OC(=O)CN(CCN(CC(=O)O)CC(=O)O)CC(=O)O.

UNSPSC 51172331 Ethylenediaminetetraacetic acid (EDTA), a Commodity code, shows minimal recent state and local procurement activity aligned with its narrow chemical specification. The three most recent opportunities tagged to this code involve drug testing services, pharmaceutical distribution, and direct-to-manufacturer prescription programs — none of which center on EDTA as a procurement line item. Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services (due July 23, 2026, estimated contract value $600,000) does reference laboratory testing methodologies including immunoassay screening and LC/MS/MS confirmation that may incorporate chelating agents in sample preparation, but the solicitation does not identify EDTA or any specific chemical reagent as a discrete deliverable or cost element. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP for generic multi-source pharmaceuticals and OTC products (proposals due March 26, 2026) and the Texas Health and Human Services Commission's RFI HHS0017013 regarding direct-to-manufacturer prescriptions (issued April 3, 2026) address pharmaceutical supply and contracting models rather than laboratory or analytical chemicals.

The code shows no meaningful recent activity reflecting state or local government direct procurement of EDTA as a standalone reagent, supply input, or service component. Issuing bodies across Texas and Minnesota have posted opportunities in adjacent pharmaceutical and diagnostic testing domains, but none explicitly solicit or price EDTA. A vendor pursuing state and local opportunities under this code should verify that target customers — laboratories, testing facilities, clinical departments within health agencies, or research institutions operated by state or local government — are actually requesting EDTA through formal solicitation channels rather than relying on routine supply-chain or standing-order mechanisms outside the RFP and RFQ processes tracked here.
