UNSPSC 51285805: Hexamine or methenamine

This classification denotes a urinary anti-infective agent with the molecular formula C6H12N4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier J50OIX95QV, chemically known as 1,3,5,7-tetraazatricyclo(3.3.1.1(sup 37))decane but more generally known as hexamine, which bears US NIH Compound Identifier 4101. European Medicines Agency schedules Methenamine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08845MIG. The term HEXAMINE is an International Non-Proprietary Name.

The World Health Organization schedules hexamine in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: C1N2CN3CN1CN(C2)C3.

UNSPSC 51285805 Hexamine or methenamine is a Commodity code. Recent state and local procurement activity under this code shows little direct alignment with the nominal scope. The two most recent opportunities tagged to this code involve pharmaceutical procurement—one a completed award through the Illinois Department of Public Health for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets via the MMCAP Infuse cooperative purchasing vehicle, and another from Seminole County, Florida for Naloxone and drug deactivation systems—neither of which is hexamine or methenamine specifically. The opportunities reflect broader pharmaceutical warehouse and emergency-response medical supply sourcing by state health departments and county health agencies, but do not demonstrate active market demand for hexamine or methenamine itself at the state and local level.

The issuing bodies include a state department of public health and a county government agency focused on community health and emergency response. The Illinois Department of Public Health contract, awarded to Chartwell Rx LLC on August 28, 2026 for $2,999,999.11 over three years under an Invitation for Bid, illustrates how jurisdictions use cooperative purchasing consortia to source pharmaceutical products with multi-year terms and renewal options. The Seminole County opportunity (IFB 60459723LAS, due July 26, 2023) sought quarterly deliveries of 1,900 units of Naloxone and 800 drug deactivation systems annually through electronic bidding. Geographic activity centers on Illinois and Florida based on recent posts. The code appears to see limited current activity specific to hexamine or methenamine supply; bidders should verify whether state and local health and emergency-management agencies are actively sourcing these chemical compounds or whether the code tagging reflects data-quality issues in the source systems.
