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, but the recent state and local opportunities tagged under it show little alignment with chemical supply procurement. Instead, the code's recent activity centers on pharmaceutical and medical supply distribution for emergency services, correctional institutions, and public health initiatives. State and local governments are buying finished pharmaceutical products—naloxone, BLS and ALS medications, prescription supplies for police departments—along with pharmacy benefit management services and medical supply vending systems. The issuing bodies span municipal fire departments, police operations, county EMS services, university health operations, and multi-jurisdictional health plans. Detroit's Office of Contracting and Procurement, Tucson Fire Department, and Williamson County EMS appear as active repeat buyers of emergency medical pharmaceuticals and supplies.

Geographic activity is concentrated in the Southwest and Southeast, with recent solicitations posted from Arizona, Texas, Florida, Georgia, and California. Tucson's City of Tucson Fire Department issued the most detailed RFP (due June 24, 2026, since revised) for BLS and ALS pharmaceuticals, supplies, and VendNovation vending machines, federally funded through ARPA, HUD, and FTA grants with Davis-Bacon and Section 3 compliance requirements and a 95 percent fill-rate service standard. The City of Detroit Office of Contracting and Procurement posted two separate RFQs for prescription drug supplies (due October 9, 2026) and medical supplies for vending machines (due September 18, 2026), both incorporating Detroit-based small-business set-asides. The City of Orem issued an RFP for a phosphorus control system for water reclamation (due October 16, 2026) that requires design, fabrication, and technical support—a materials and equipment play distinct from the pharmaceutical focus of most other opportunities under this code. The code shows material misalignment between its nominal scope and actual procurement activity, warranting verification of the correct chemical-commodities code for hypophosphorous acid sourcing.
