UNSPSC 51384603: Antipyrine or phenazone or phenazon or analgesine

This classification denotes a nonsteroidal antiinflammatory drug with the molecular formula C11H12N2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier T3CHA1B51H, chemically known as 2,3-dimethyl-1-phenylpyrazol-5-one but generally known as antipyrine, which bears US NIH Compound Identifier 2206. Antipyrine most often comes in base, iodide, and salicylate forms. European Medicines Agency schedules Phenazone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09753MIG.

The term PHENAZONE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 13, No. 12, 1959, List 3). World Health Organization schedules antipyrine in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: CC1=CC(=O)N(N1C)C2=CC=CC=C2.

UNSPSC 51384603 Antipyrine or phenazone or phenazon or analgesine is a Commodity code that nominally covers a specific fever-reducing compound, but the recent state and local procurement activity under this code shows little alignment with the code's stated scope. Seminole County, Florida, posted a competitive invitation for bids (IFB 60459723LAS) for naloxone and drug deactivation systems—products unrelated to antipyrine or phenazone—suggesting either a coding mismatch in the county's procurement system or a data-quality issue in how the opportunity was tagged. The solicitation itself is straightforward: the county seeks 1,900 units of naloxone and 800 safe drug deactivation systems annually through quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida, with all shipping and delivery costs to be included in vendor pricing. Bidders must comply with drug-free workplace certification, E-Verify confirmation of employee eligibility, and specified insurance coverages including workers' compensation, commercial general liability, and professional liability.

No other recent state and local opportunities appear under this code. The single Seminole County bid (due July 26, 2023, with a posted date of June 30, 2026) carries contradictory dates and does not reflect current procurement activity under the antipyrine code itself. The contract includes a two-year initial term with a one-year renewal option and is potentially FEMA-funded, introducing compliance obligations under the Clean Air Act and Federal Water Pollution Control Act. Firms evaluating this code should treat the current activity block as a misclassification signal rather than a meaningful market opportunity and should verify whether antipyrine or related fever-reduction compounds are actually being solicited by state and local health departments, pharmacies, or correctional facilities under this or a related code.
