UNSPSC 51283918: Sulfamethizole

This classification denotes a sulfonamide anti-infective agent with the molecular formula C9H10N4O2S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 25W8454H16, chemically known as 5-methyl-2-sulfanilamido-1,3,4-thiadiazole but generally known as sulfamethizole, which bears US NIH Compound Identifier 5328. European Medicines Agency schedules Sulfamethizole in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10710MIG.

UNSPSC 51283918 Sulfamethizole is a Commodity code for a specific pharmaceutical active ingredient; however, the recent state and local opportunities tagged under this code do not reflect procurement of sulfamethizole itself. Instead, the tagged solicitations document purchases of unrelated pharmaceutical products—doxycycline hyclate, ciprofloxacin hydrochloride, and naloxone—through different procurement vehicles and issuing bodies. This code shows little relevant recent activity aligned with its nominal scope.

The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through the MMCAP Infuse cooperative purchasing consortium to Chartwell Rx LLC on August 28, 2026, for doxycycline hyclate 100mg and ciprofloxacin hydrochloride 500mg tablets under Invitation for Bid 26-482DPH-PREPDB53392, with a total award of $2,999,999.11 over the contract life including renewal options. Seminole County, Florida released an Invitation for Bid on June 30, 2026, to procure 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the county's community health building. The mismatch between the code's sulfamethizole designation and the actual pharmaceutical products being solicited suggests either a cataloging error in the source data or a broader tagging convention that does not map cleanly to this specific commodity. Business development professionals should verify the actual pharmaceutical products required in any state or local opportunity before pursuing under this code.
