UNSPSC 12352135: Propylene glycol

A liquid alcohol used as a solvent in antifreeze and in the food, plastics, and perfume industries. Also called 1,2-propanediol or propane-1,2-diol.

UNSPSC 12352135 Propylene glycol (Commodity) comprises specialty chemicals and reagents that state and local governments procure for forensic analysis, laboratory testing, public health diagnostics, water treatment, and heating/cooling system maintenance. Recent solicitations show state and local bodies purchasing propylene glycol derivatives—particularly inhibited propylene glycol for HVAC systems—alongside a broader ecosystem of forensic-grade reference materials, DNA sequencing consumables, diagnostic testing kits, and laboratory chemical supplies. While the code name references propylene glycol specifically, the actual buying patterns reveal that governments source this commodity as part of larger consumables contracts that bundle laboratory reagents, forensic supplies, and chemical inventory. Issuing bodies span state forensic and public health laboratories (Texas Department of Public Safety, District of Columbia Department of Forensic Sciences, State of California), municipal water and utility departments (City of Arlington, City of Meriden), county government (Harris County Sheriff's Office, Gwinnett County), transit and public-utility authorities, and school districts (Buffalo Public Schools). State laboratories and university procurement offices (Texas A&M University) appear as repeat buyers. The geographic spread includes Texas, California, the District of Columbia, Georgia, Connecticut, and New York, with Texas and California showing the most recent high-volume solicitation activity in forensic and laboratory consumables.

Representative recent opportunities include the Texas Comptroller of Public Accounts' IFB 304T-27-175A1.1 (posted September 23, 2026, due October 20, 2026) for forensic laboratory consumables and reagents supporting DNA analysis and drug screening across the Texas Department of Public Safety and Parks and Wildlife, with single-source vendor specifications and quantities ranging from 8 to 5,000 units per line item; Buffalo Public Schools' RFB 26-0626-080 (posted May 11, 2026, due May 27, 2026) for 40% inhibited propylene glycol delivered by tanker truck to three district buildings plus four 275-gallon plastic totes; and the City of Meriden's ITB B026-55 (posted June 9, 2026, due June 25, 2026) for water treatment chemicals including liquid caustic soda, sodium permanganate, and sodium fluoride under Build America Buy America Act compliance. The District of Columbia Department of Forensic Sciences, State of California, and Harris County also posted consumables and reagent solicitations in this window, though several contained limited scope detail in available summaries. Response windows typically run 5–21 days from posting to due date.
