This classification denotes an anti-bacterial agent 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 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 6-(2-ethoxy-1-naphthamido)-3,3-dimethyl-7-oxo- but more generally known as nafcillin sodium, which bears US NIH Compound Identifier 8982. European Medicines Agency schedules Nafcillin sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03375MIG.

UNSPSC 51283513 Nafcillin sodium is a Commodity code identifying a specific antibiotic pharmaceutical product, but the recent state and local opportunities tagged under this code do not reflect procurement of nafcillin itself. Instead, the tagged records show acquisitions of other pharmaceuticals—doxycycline hyclate, ciprofloxacin hydrochloride, and naloxone—through direct purchase and piggyback contracts. State and local health departments and county public health agencies use UNSPSC pharmaceutical commodity codes to classify drugs procured for emergency preparedness stockpiles, community health clinics, and public health response programs. Issuing bodies include state health departments and county health and emergency management offices, which source these products through both competitive sealed bids and established pharmaceutical cooperative purchasing vehicles such as MMCAP Infuse.

The Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical warehouse contract to Chartwell Rx LLC on August 28, 2026, through the MMCAP Infuse consortium for doxycycline hyclate 100mg and ciprofloxacin hydrochloride 500mg tablets under IFB 26482DPHPREPDB53392, covering a 12-month initial term with two one-year renewal options. Seminole County, Florida issued IFB 60459723LAS on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually, with quarterly deliveries to the Seminole County Community Health Building and a response deadline of July 26, 2026. Recent activity appears concentrated in Illinois and Florida, though the mismatch between the code's nominal product (nafcillin sodium) and the actual drugs being procured suggests either miscoding in the source data or limited current nafcillin demand in state and local emergency health procurement. Vendors pursuing this code should verify that current bid opportunities match their product lines, as the taxonomy classification may not reliably predict the specific pharmaceutical being requested.
