UNSPSC 12352146: Di methyl disulphiide

Dimethyl disulfide (DMDS) is an organic disulfide that is methane in which one of the hydrogens has been replaced by a methylsulfonyl group. It has a role as a xenobiotic metabolite.

UNSPSC 12352146 Dimethyl disulphide (Commodity) appears in state and local solicitations principally as a chemical component within water treatment and facility disinfection systems rather than as a standalone product. Recent opportunities show state and local governments purchasing disinfectant-generation equipment and multi-chemical supply contracts for wastewater and drinking water treatment, with hypochlorous acid generators and treatment chemicals dominating the posted activity. The code's nominal product scope does not align closely with the work actually being solicited, which focuses on end-use disinfection and water treatment applications rather than dimethyl disulphide as a discrete chemical input. County and municipal water utilities and facility management operations are the primary issuing bodies, with procurement driven by water treatment standards compliance and facility sanitation requirements.

Escambia County, Florida has posted two separate hypochlorous acid generator procurements: a sole-source contract (SSC2526004, due February 25, 2026) requiring EPA-approved equipment capable of on-site production and 24/7 maintenance support, and a competitive RFP (PD2526083, due August 11, 2026) for purchase, installation, and maintenance of a generator meeting similar operational and safety specifications. The City of Flowery Branch, Georgia issued an Invitation for Bid (26-007, due April 21, 2026) for a five-year supply contract covering seven chemical products including sodium hypochlorite bleach, aluminum chlorohydrate, caustic soda, citric acid, fluoride, and polymer, with mandatory pre-bid attendance, mandatory site visits to the Well Building and Wastewater Treatment Plant, and delivery requirements specifying box trucks equipped with liftgates and returnable totes. The City of Flowery Branch procurement noted current suppliers Brenntag Mid-South, Inc. and R&M Water Solutions, LLC. Recent activity concentrates in Florida and Georgia, with water treatment infrastructure expansion driving procurement — the Flowery Branch wastewater treatment plant is scheduled to expand from 0.91 million gallons per day to 1.5 million gallons per day between July and August 2026. The code shows limited recent activity directly aligned to dimethyl disulphide procurement.
