UNSPSC 51282951: Nalidixic acid

This classification denotes a urinary anti-infective agent and quinolone antibiotic with the molecular formula C12H12N2O3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3B91HWA56M, chemically known as 1,8-naphthyridine-3-carboxylic acid, 1-ethyl-1,4-dihydro-7-methyl-4-oxo- but generally known as nalidixic acid, which bears US NIH Compound Identifier 4421. European Medicines Agency schedules Nalidixic acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09138MIG.

UNSPSC 51282951 Nalidixic acid is a Commodity code that nominally designates a specific antibiotic compound, but recent state and local procurement activity under this code shows minimal alignment with the code's abstract scope. The most recent opportunities tagged to this code involve pharmaceutical procurement — including antibiotic tablets (Doxycycline Hyclate and Ciprofloxacin Hydrochloride) and harm-reduction supplies (Naloxone and drug deactivation systems) — rather than nalidixic acid itself as a distinct line item. These solicitations reflect state and local health departments' and county public health systems' recurring need for pharmaceutical inventory through piggyback cooperative purchasing vehicles and direct competitive bidding. The issuing bodies include state health departments and county health systems; the Illinois Department of Public Health and Seminole County, Florida appear in the recent record.

Activity under this code concentrates in Illinois and Florida based on posted opportunities. The Illinois Department of Public Health awarded a completed piggyback pharmaceutical warehouse order through the MMCAP Infuse cooperative purchasing vehicle to Chartwell Rx LLC on August 28, 2026, for antibiotic tablets totaling $2,999,999.11 over the contract lifecycle with 12-month initial term and two renewal options. Seminole County, Florida released an IFB on June 30, 2026, for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building, requiring electronic bid submission through the county e-Procurement Portal with a response deadline of July 26, 2023, at 2:00 pm. The code shows sparse recent activity and the opportunities posted do not consistently track to nalidixic acid specifically, suggesting limited relevance for vendors focused on that particular pharmaceutical product line.
