This classification denotes a beta-lactam antibiotic with the molecular formula C21H21N2O5S.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 49G3001BCK, chemically known as monosodium (2s,5r,6r)-6-(2-ethoxy-1-naphthamido)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylate monohydrate, but more generally known as nafcillin sodium monohydrate, which bears US NIH Compound Identifier 5282391.

European Medicines Agency schedules nafcillin sodium monohydrate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09118MIG. Most nations, for tariff purposes, schedule nafcillin sodium monohydrate under HS 29411090. SMILES: CCOC1CCC2CCCCC2C1C(=O)N[C@H]3[C@@H]4N(C3=O)[C@H](C(S4)(C)C)C(=O)[O-].O.[NA+].

UNSPSC 51283515 Nafcillin sodium monohydrate is a Commodity code that has generated minimal recent state and local procurement activity directly aligned with the pharmaceutical ingredient itself. State and local governments soliciting under this code are actually buying broader medical and pharmaceutical products and services — naloxone and drug deactivation systems, medical and first aid supplies for emergency response, and generic multi-source pharmaceuticals through cooperative purchasing vehicles — rather than narrowly specified antibiotic compounds like nafcillin. The issuing bodies include county health departments, city fire rescue divisions, and state health and human services agencies that procure on behalf of health systems and emergency medical services, often coordinated through multistate cooperative purchasing alliances such as MMCAP.

Recent opportunities show activity in Florida, Texas, and Minnesota. Seminole County, Florida posted IFB 60459723LAS in June 2026 seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with deliveries to the Seminole County Community Health Building; the bid deadline was July 26, 2023. The City of Tampa posted ITB 26P00145 in March 2026 for 169 line items of medical and first aid supplies for the Tampa Fire Department Rescue Division, with an estimated contract value of $700,000.00 and a March 13, 2026 bid deadline; this procurement is sheltered for certified Small Local Business Enterprises with a 5 percent bid discount. The Minnesota Department of Administration issued RFP S1070000015802 through MMCAP in January 2026 for generic multi-source pharmaceuticals and OTC products, with proposals due March 26, 2026 and distribution to authorized wholesalers by May 15, 2026. The Texas Health and Human Services Commission posted RFI HHS0017013 in April 2026 to gather market intelligence on direct-to-manufacturer prescription programs, signaling future procurement interest in innovative pharmacy benefit models rather than traditional pharmaceutical commodity acquisition.
