UNSPSC 12352153: Sulfolane

Sulfolane (also tetramethylene sulfone, systematic name: 1l6-thiolane-1,1-dione) is an organosulfur compound, formally a cyclic sulfone, with the formula (CH2)4SO2. It is a colorless liquid commonly used in the chemical industry as a solvent for extractive distillation and chemical reactions

UNSPSC 12352153 Sulfolane (Commodity) represents chemical disinfectants and treatment products that state and local governments procure for facility sanitation, wastewater treatment, and drinking water processing. Recent solicitations show demand spanning hypochlorous acid generators for on-site production of disinfectants, sodium hypochlorite bleach for both drinking water and wastewater applications, and a full suite of water treatment chemicals including aluminum chlorohydrate, caustic soda, citric acid, fluoride compounds, and polymers. Issuing bodies are primarily municipal utilities and county facilities — the City of Flowery Branch and Escambia County Board of County Commissioners have both posted active procurements under this code within the past six months. The work encompasses equipment purchase and installation with ongoing maintenance contracts, supply agreements for bulk chemical delivery with strict compliance to drinking water standards (NSF/ANSI/CAN 60 certification required), and cybersecurity-enabled monitoring systems for real-time EPA compliance reporting.

Recent activity concentrates in Florida, with Escambia County issuing a sole source procurement for a hypochlorous acid generator due February 25, 2026, and a subsequent competitive RFP (solicitation PD2526083) due August 11, 2026 for purchase, installation, and maintenance of similar equipment across county facilities. The City of Flowery Branch issued an Invitation for Bid (26-007) on March 4, 2026 for a five-year supply contract covering seven chemical products with mandatory pre-bid attendance on March 24, 2026 at City Hall and written questions due March 27, 2026; bids closed April 21, 2026. Current suppliers in the Flowery Branch contract include Brenntag Mid-South, Inc. and R&M Water Solutions, LLC. Delivery requirements are demanding — the Flowery Branch IFB specifies box trucks equipped with liftgates, 5–7 day delivery windows, returnable totes (330-gallon preferred), and city staff presence at all designated sites; bonding, insurance, and Net 30 payment terms apply. The code shows limited recent activity outside Florida; geographic spread in the source material is confined to that state.
