UNSPSC 51282521: Cefadroxil monohydrate

This classification denotes a cephalosporin antibiotic with the molecular formula C16H17N3O5S.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 280111G160, chemically known as 5-thia-1-azabicyclo(4.2.0)oct-2-ene-2-carboxylic acid, 7-((amino(4-hydroxyphenyl)acetyl)amino)-3-methyl-8-oxo-, (6r-(6-alpha,7-beta(r*)))- but more generally known as cefadroxil, which bears US NIH Compound Identifier 2610. Cefadroxil most often comes in base, hydrate, and hemihydrate forms.

UNSPSC 51282521 Cefadroxil monohydrate is a Commodity code that does not reflect the actual procurement activity currently being tagged under it in state and local markets. Recent opportunities posted under this code are purchasing naloxone and drug deactivation systems, direct-to-manufacturer prescription programs, emergency medical and first aid supplies for fire departments, and generic multi-source pharmaceuticals through cooperative purchasing arrangements—none of which involve cefadroxil, an antibiotic oral medication. The mismatch between the code's nominal scope and the work actually being solicited suggests that state and local procurement offices are applying this code inconsistently or that the opportunities have been miscategorized in the source system.

The geographic and issuing-body spread across recent opportunities spans Florida (Seminole County), Texas (Health and Human Services Commission), and Minnesota multistate cooperative purchasing (MMCAP), with the City of Tampa also active in the region. Seminole County issued IFB 60459723LAS on June 30, 2026, for 1,900 units of naloxone and 800 safe drug deactivation systems annually with a July 26, 2023, response deadline. The Texas HHS Commission posted RFI HHS0017013 on April 3, 2026, to explore direct-to-manufacturer prescription program vendors. The City of Tampa's Purchasing Department issued ITB 26P00145 on March 25, 2026, for 169 line items of medical and first aid supplies for the Fire Department Rescue Division, with a $700,000 estimated contract value and a sheltered-market set-aside for certified Small Local Business Enterprises. MMCAP posted RFP S1070000015802 on January 20, 2026, for generic multi-source pharmaceuticals and OTC products with a March 26, 2026, response deadline. Given the lack of alignment between the code definition and recent solicitations, this code shows little relevant purchasing activity for business development purposes.
