UNSPSC 51283713: Cefaclor anhydrous

This classification denotes a cephalosporin antibiotic with the molecular formula C15H14ClN3O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3Z6FS3IK0K, chemically known as 5-thia-1-azabicyclo(4.2.0)oct-2-ene-2-carboxylic acid, 7-(((2r)-2-amino-2-phenylacetyl)amino)-3-chloro-8-oxo-, (6r,7r)-, but more generally known as cefaclor anhydrous, which bears US NIH Compound Identifier 40958.

European Medicines Agency schedules cefaclor anhydrous or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06163MIG. Most nations, for tariff purposes, schedule cefaclor anhydrous under HS 29419000. Cefaclor anhydrous bears US NLM identifiers UMLS ID C2699131 and NCI Concept Code C76033. SMILES: C1CCC(CC1)[C@H](C(=O)N[C@H]2[C@@H]3N(C2=O)C(=C(CS3)CL)C(=O)O)N.

UNSPSC 51283713 Cefaclor anhydrous is a Commodity code for a specific broad-spectrum antibiotic formulation, but the recent state and local contract opportunities tagged to this code show no procurement activity for cefaclor itself. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium in August 2026 for Doxycycline Hyclate and Ciprofloxacin Hydrochloride—different antibiotic classes entirely—while Seminole County, Florida released an IFB in June 2026 for Naloxone and Safe Drug Deactivation Systems, which fall outside pharmaceutical antibiotics altogether. The mismatch indicates either tagging errors in the procurement database or that cefaclor is not actively solicited at the state and local level under current market conditions.

State and local government procurement activity does not support recent opportunities for cefaclor anhydrous specifically. The tagged opportunities reflect broader pharmaceutical supply chain activity among state health departments and counties, but neither addresses the commodity code's nominal scope. Without concrete recent solicitations for cefaclor products, the code shows little actionable signal for business development targeting state and local buyers.
