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, a Commodity code, shows no recent state and local procurement activity aligned with its nominal scope—the chemical product sulfolane itself. The three most recent opportunities tagged to this code represent unrelated work: herbicide purchasing (City of Philadelphia), hypochlorous acid generator acquisition and maintenance (Escambia County Board of County Commissioners), and sludge hauling and liquid waste disposal services (Brazos River Authority). The mismatch between the code's chemical-product definition and the actual solicitations posted under it signals either a data-classification error in the source records or inconsistent coding practice by the issuing bodies, and suggests that the code does not currently represent an active procurement category at the state and local level.

Given the absence of relevant recent opportunities, this code warrants close monitoring but carries no immediate pursuit signal. Vendors with sulfolane products or related specialty chemical services should verify that future state and local opportunities are correctly coded before investing in business development against this category.
