UNSPSC 12352152: Ethyl mercaptan

Ethyl mercaptan is a colorless or yellowish liquid or a gas with a pungnet, garlic or skunk-like odor. It is used as an additive to odorless gases likebutane, porpane, and petroleum to give them a warning odor. Also used in the manufacture of fungicides, pharmaceuticals, insecticides, resins and other chemicals.

UNSPSC 12352152 Ethyl mercaptan, a Commodity code, covers specialized chemical disinfectants and treatment products for municipal and county facilities, though recent state and local solicitations under this code show a significant mismatch between the nominal commodity and what is actually being procured. The recent opportunities reflect demand for hypochlorous acid generators and water treatment chemicals rather than ethyl mercaptan itself. State and local buying under this code spans county governments and municipal utilities, with Escambia County, Florida and the City of Flowery Branch, Georgia appearing as active purchasers in the first half of 2026. The scope of work includes purchase and installation of on-site chemical generation equipment, supply contracts for bulk water treatment chemicals, and associated maintenance and personnel training.

Escambia County issued two separate opportunities for hypochlorous acid generator systems—a sole source procurement (SSC2526004) released February 18, 2026 with a due date of February 25, 2026, and a competitive RFP (PD2526083) posted June 30, 2026 with proposals due August 11, 2026. The City of Flowery Branch issued an Invitation for Bid (26-007) on March 4, 2026 for a five-year supply contract covering seven water treatment chemicals including sodium hypochlorite, aluminum chlorohydrate, caustic soda, citric acid, hydrofluosilicic acid, and polymer products, with a mandatory pre-bid meeting scheduled for March 24, 2026 at 9:30 a.m. EST and bids due April 21, 2026. The Flowery Branch contract references current suppliers Brenntag Mid-South, Inc. and R&M Water Solutions, LLC, with baseline pricing at $0.525 per pound for ACH and $0.279 per pound for caustic soda. Activity is concentrated in Florida and Georgia, with no indication of broader geographic spread across the recent opportunities.
