UNSPSC 12361505: Hypophosphorous acid

A phosphorus oxoacid and a powerful reducing agent with molecular formula H3PO2. It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols and is used in the formulation of pharmaceuticals, discoloration of polymers, water treatment, retrieval of precious or non-ferrous metals. Its main use is for electroless plating. Currently considered a controlled drug by the US Government because it can reduce elemental iodine to form hydroiodic acid, which is a reagent effective for reducing ephedrine or pseudoephedrine to methamphetamine.

UNSPSC 12361505 Hypophosphorous acid is a Commodity code that sits at odds with the actual state and local procurement activity posted under it. The recent opportunities tagged to this code show minimal or no direct purchasing of hypophosphorous acid; instead, the opportunities center on emergency medical services pharmaceuticals, supplies, and related services — including EMS medical and pharmaceutical items, naloxone and drug deactivation systems, BLS/ALS pharmaceuticals and supplies with vending and inventory management, pharmacy benefit management services, and on-site pharmacy operations. The mismatch suggests either tagging error or a very narrow use of hypophosphorous acid within broader pharmaceutical procurement that the source does not isolate.

Recent activity spans county emergency management, municipal fire departments, and regional health plans across Texas, Florida, and Arizona. Williamson County, Texas posted an IFB for EMS medical and pharmaceutical items (26IFB63, due August 4, 2026) through its purchasing office in Georgetown; the City of Tucson Fire Department posted an RFP for BLS and ALS pharmaceuticals, supplies, and VendNovation vending systems (RFP 260217, due June 24, 2026), federally funded through ARPA, HUD, and FTA grants with compliance obligations including prevailing wage, Davis-Bacon, DBE participation, and Section 3 labor requirements; Seminole County, Florida solicited naloxone and safe drug deactivation systems (IFB 60459723LAS, due July 26, 2023) with quarterly deliveries to the county health building in Sanford; and Inland Empire Health Plan in San Bernardino County, California requested proposals for pharmacy benefit manager services (RFP 2607198, due July 15, 2026). The code shows little relevant recent activity directly tied to hypophosphorous acid procurement in state and local markets.
