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 is a Commodity code that nominally describes a chemical compound used as an odorant in natural gas and other industrial applications, but recent state and local solicitations tagged with this code show minimal alignment with that scope. The three most recent opportunities under this code—a City of Philadelphia herbicide micro-order purchase (RFQ, due October 14, 2026), an Escambia County hypochlorous acid generator procurement (RFP, due August 11, 2026), and a Brazos River Authority sludge hauling and waste disposal services contract (IFB, due August 20, 2026)—address herbicides, water disinfection equipment, and waste management rather than ethyl mercaptan or its industrial derivatives. The issuing bodies span municipal procurement (Philadelphia), county government (Escambia County, Florida), and special-purpose districts (Brazos River Authority, Texas), suggesting the code is being applied inconsistently across jurisdictions or may be a data-entry misclassification in the source systems of the posting agencies.

The geographic spread covers Texas, Florida, and Pennsylvania based on recent postings, with no concentration evident. Because the three recent opportunities bear no substantive relationship to ethyl mercaptan or its chemical class, this code shows little relevant recent activity for vendors focused on specialty chemicals or odorant compounds. Business development professionals should verify the correct UNSPSC classification for ethyl mercaptan-related opportunities directly with procurement offices before pursuing; the current tagging suggests either systematic miscoding or use of this commodity code as a placeholder for unrelated goods and services.
