UNSPSC 51283421: Fenbenicillin

This classification denotes a penicillin antibiotic, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 641EDA6X6L. European Medicines Agency schedules Fenbenicillin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07542MIG. Fenbenicillin generally arises in the molecular formula C22H22N2O5S.

The term FENBENICILLIN is an International Non-Proprietary Name or INN (see World Health Organization INN reference publication, volume 19 1975, list 5.) FENBENICILLIN is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: S1C2N(C(C1(C)C)C(=O)O)C(=O)C2NC(=O)C(OC1CCCCC1)C1CCCCC1.

UNSPSC 51283421 Fenbenicillin (Commodity) shows minimal recent state and local procurement activity directly aligned with the code's scope. The two recent opportunities tagged to this code—an Illinois Department of Public Health pharmaceutical warehouse contract and a Seminole County, Florida naloxone and drug deactivation systems procurement—do not reflect fenbenicillin purchasing. The Illinois award supplied Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets through a piggyback agreement with Chartwell Rx LLC, while the Seminole County solicitation sought naloxone and harm-reduction equipment for community health. Neither opportunity involves fenbenicillin, an antibiotic pharmaceutical, suggesting either data misclassification or sporadic use of this code for broad pharmaceutical procurements that fall outside its nominal definition.

Recent activity appears concentrated in Florida and Illinois, with the Illinois Department of Public Health and Seminole County as the named issuing bodies. The Illinois contract, completed in August 2026 through the MMCAP Infuse cooperative purchasing consortium, awarded $2.999 million over three years on an IFB basis. The Seminole County IFB, posted June 30, 2026 with a July 26, 2026 response deadline, sought annual supplies with quarterly deliveries and carried potential FEMA funding with associated federal compliance requirements. No other jurisdictions or recent opportunities under this code appear in the source material. The code warrants watch status rather than active pursuit unless your firm has fenbenicillin or related antibiotic inventory to position—the tagged opportunities reflect a broader pharmaceutical-supply classification problem rather than sustained demand for this specific agent.
