UNSPSC 51473702: Zinc phenolsulfonate

This classification denotes a topical anti-infective agent with the molecular formula 2C6H5O4S.Zn, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4O71YT5YB5, chemically known as zinc-1,4-phenolsulfonate but generally known as zinc phenolsulfonate, which bears US NIH Compound Identifier 31391. European Medicines Agency schedules Zinc phenolsulfonate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB33888. As of Q4 2014, ZINC PHENOLSULFONATE remains the US FDA Preferred Term for this commodity.

Zinc phenolsulfonate bears US NLM identifiers UMLS ID C0301434 and NCI Concept Code C84250. SMILES: [ZN].S(=O)(=O)(O)C1CCC(O)CC1.S(=O)(=O)(O)C1CCC(O)CC1.

UNSPSC 51473702 Zinc phenolsulfonate is a Commodity code that in state and local procurement activity covers chemical compounds and specialty additives procured as components within broader janitorial, operational, pharmaceutical, and healthcare-related supply contracts. The code itself names a specific industrial chemical, but state and local jurisdictions typically solicit it as part of multi-line consumable or pharmaceutical supply agreements rather than as a standalone product. Issuing bodies across the code range from county boards of commissioners and state health or procurement departments to cooperative purchasing alliances serving multiple states and local agencies. Recent activity shows county governments and state-administered multistate cooperative purchasing vehicles as the primary buyers.

The two most recent state and local opportunities tagged to this code originate in Florida and Minnesota. Hillsborough County Board of County Commissioners issued ITB2600319 on July 7, 2026 for janitorial and operational supplies including consumables for 47 fire stations across a one-year term with an estimated contract value of $765,679.84, with bids due July 24, 2026. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP posted January 20, 2026 for generic multi-source pharmaceuticals and over-the-counter products to serve participating state and local government facilities, with proposals due March 26, 2026 and contract effectiveness set for July 1, 2026. The mismatch between the code's nominal scope (zinc phenolsulfonate, a specific corrosion inhibitor and disinfectant chemical) and these broad janitorial and pharmaceutical supply solicitations suggests the code sees limited dedicated activity; procurement officers may be applying it at the line-item level within larger consumable agreements rather than through standalone chemical procurement.
