UNSPSC 51285803: Hexamidine diisethionate

This classfication denotes an antibiotic with the molecular formula C20H26N4O2.2C2H6O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 023XA5Z50L, chemically known as 4,4'-(hexamethylenedioxy)dibenzamidine bis(2-hydroxyethanesulphonate), but more generally known as hexamidine diisethionate, which bears US NIH Compound Identifier 3080571. European Medicines Agency schedules hexamidine diisethionate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08029MIG.

UNSPSC 51285803 Hexamidine diisethionate is a Commodity code with minimal recent state and local procurement activity directly tied to its nominal scope. The recent opportunities tagged under this code do not reflect purchasing of hexamidine diisethionate itself; instead, they capture acquisitions of naloxone, drug deactivation systems, medical and first aid supplies, and generic pharmaceuticals through various issuing bodies. Hexamidine diisethionate is a preservative and antimicrobial agent used in pharmaceuticals, cosmetics, and medical products, but the current opportunity set does not demonstrate active demand for it as a standalone line item or input material under this code.

State and local jurisdictions posting opportunities under this code include a Florida county (Seminole County), a Texas state health agency (Texas HHS Commission), a municipal fire department (City of Tampa), and a multistate cooperative purchasing alliance serving state and local entities (MMCAP, administered by Minnesota Department of Administration). The geographic spread reflects activity in Florida, Texas, and the Upper Midwest with multistate reach through cooperative contracting. Representative recent opportunities include Seminole County's IFB for naloxone and drug deactivation systems (due July 26, 2026, 1,900 units of naloxone and 800 deactivation systems annually); the City of Tampa's IFB for medical and first aid supplies to the Tampa Fire Department Rescue Division (due March 13, 2026, estimated contract value $700,000, sheltered for certified Small Local Business Enterprises); and MMCAP's RFP for generic multi-source pharmaceuticals and OTC products (due March 26, 2026, with award effective July 1, 2026). The code shows little actionable activity for firms supplying hexamidine diisethionate directly; the mismatch between code and solicitation content suggests either misclassification by issuing bodies or use of this code as a catch-all for pharmaceutical and medical supply categories.
