UNSPSC 51283900: Sulfonamide antibacterials

This classification denotes a group of compounds that contain the structure SO2NH2. Members of this group, also known as sulfa drugs, are derivatives of sulfanilamide (an amide composed of a sulfonyl group connected to an amine, hence the names Sulfon-amide, Sulfonamide, Sulfonamides, or as here, Sulfonamide Antibacterials), which competitively inhibit folic acid synthesis in microorganisms, and are bacteriostatic. They have been largely supplanted by more effective and less toxic antibacterials.

UNSPSC 51283900 Sulfonamide antibacterials is a Class code covering antibiotic pharmaceutical products that state and local health departments and county health agencies procure for community health programs, emergency preparedness, and disease treatment initiatives. Recent activity shows procurement of specific sulfonamide and related antibiotic formulations—Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—through cooperative purchasing vehicles and direct competitive bids. Issuing bodies include state health departments and county governments; the Illinois Department of Public Health and Seminole County, Florida are recent buyers.

The Illinois Department of Public Health awarded a $2.999 million piggyback pharmaceutical contract through the MMCAP Infuse consortium to Chartwell Rx LLC on August 28, 2026 via Invitation for Bid (IFB), covering a 12-month initial term with two one-year renewal options. Seminole County, Florida issued an IFB (Number IFB60459723LAS) on June 30, 2026 with a July 26, 2023 response deadline for procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually, though the opportunity record notes a discrepancy in the posted and deadline dates that suggests data quality issues in the source. Activity is concentrated in the Southeast and Midwest, with cooperative purchasing vehicles such as MMCAP Infuse serving as aggregation mechanisms for statewide health system procurement. Contracts typically include initial two- to three-year terms with renewal options and quarterly or fixed-schedule delivery requirements to designated health facilities.
