UNSPSC 51283605: Rifametane

This classification denotes an antitubercular agent with the molecular formula C44H60N4O12, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier 1PUG6262HX, chemically known as rifamycin, 3-(((1-(diethylamino)ethylidene)hydrazono)methyl)- but more generally known as rifametane, which bears U.S. National Institutes of Health Compound Identifier 9571071. The European Medicines Agency schedules Rifametane in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10306MIG.

UNSPSC 51283605 Rifametane is a Commodity-tier code that nominally designates pharmaceutical active ingredients, yet the recent state and local contracting activity tagged to this code shows minimal alignment with rifametane itself. The Illinois Department of Public Health's August 2026 piggyback pharmaceutical warehouse order through MMCAP Infuse to Chartwell Rx LLC procured Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—both broad-spectrum antibiotics unrelated to rifametane—under a $2,999,999.11 contract spanning an initial 12-month term plus two renewal options. Seminole County, Florida's June 2026 IFB sought 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually for community health delivery, also unrelated to rifametane. State and local procurement appears to use this code inconsistently; recent activity does not reflect the rifametane pharmaceutical category the code nominally names.

The geographic activity centers on Florida and Illinois, though the sample is too small to establish meaningful regional concentration. Issuing bodies include state health departments and county public health purchasing offices. The Seminole County procurement, posted June 30, 2026 with a July 26, 2023 due date (a temporal discrepancy in the source), called for electronic submission through the county e-Procurement Portal with quarterly deliveries and included FEMA compliance requirements. Business development professionals pursuing pharmaceutical supply opportunities with state and local agencies should treat this code's recent tagging record as unreliable; the actual commodity classification of active pharmaceutical ingredients, antibiotic tablets, and emergency medical supplies does not track the rifametane designation and warrants direct verification against specific RFP or RFQ scope language before bid preparation.
