UNSPSC 51241253: Tioxolone

This classification denotes an astringent with the molecular formula C7H4O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier S0FAJ1R9CD, chemically known as 1,3-benzoxathiol-2-one, 6-hydroxy- but generally known as tioxolone, which bears US NIH Compound Identifier 72139. European Medicines Agency schedules Tioxolone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11100MIG.

UNSPSC 51241253 Tioxolone is a Commodity code that in practice covers chemical treatment products for municipal water and wastewater systems, though recent state and local solicitations show little direct procurement activity under this specific code designation. The City of Austin's IFB 2200 CSH1061, posted July 27, 2026 with bids due August 25, 2026, requests liquid aluminum sulfate (alum) for phosphorus removal at Austin Water's wastewater treatment facility—a chemical coagulant application aligned with the code's scope. However, the second recent opportunity, City of Tampa Fire Rescue's ITB 25-P-00157 for medical aid supplies, is unrelated to the code's intended purpose and reflects a tagging mismatch rather than actual procurement demand under this Commodity classification. Water and wastewater utilities appear to be the primary issuing bodies when the code does see activity; specialized treatment chemicals for municipal infrastructure drive the real procurement demand.

Geographic activity under this code is limited to the opportunities identified: Austin, Texas (IFB 2200 CSH1061) and Tampa, Florida (ITB 25-P-00157), though the Tampa solicitation is not a true application of the code. The Austin opportunity is representative of the genuine work being solicited—the City of Austin's alum procurement for wastewater treatment requires NSF approval, AWWA B403 compliance, unpackaged liquid at 47%–49% concentration, an estimated 179,200 gallons annually, and delivery to a treatment facility. Bidders must demonstrate manufacturer or authorized dealer status, maintain 9,000 gallons minimum inventory, identify a primary distribution facility within 500 miles, and provide three current Texas municipal references. The contract carries local business and small business preference discounts of 5% and 3% respectively, unit pricing firm for 12 months thereafter subject to a 25% price-adjustment cap indexed to the Producer Price Index. This code shows sparse recent activity overall; procurement professionals should monitor water utility RFQs and IFBs for chemical treatment opportunities rather than expect consistent volume under this specific classification.
