UNSPSC 51283514: Nafcillin sodium anhydrous

This classification denotes a beta-lactam antibiotic with the molecular formula C21H21N2O5S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier SY07234TTS, chemically known as sodium 6-(2-ethoxy-1-naphthamido)penicillanate, but more generally known as nafcillin sodium anhydrous, which bears US NIH Compound Identifier 64712. European Medicines Agency schedules nafcillin sodium anhydrous or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09118MIG.

Most nations, for tariff purposes, schedule nafcillin sodium anhydrous under HS 29411090. Nafcillin sodium anhydrous bears US NLM identifiers UMLS ID C2698426 and NCI Concept Code C76224. SMILES: CCOC1CCC2CCCCC2C1C(=O)N[C@H]3[C@@H]4N(C3=O)[C@H](C(S4)(C)C)C(=O)[O-].[NA+].

UNSPSC 51283514 Nafcillin sodium anhydrous is a Commodity code representing a specific pharmaceutical active ingredient, but recent state and local contract opportunities show minimal direct activity tied to this code. The two posted opportunities in the recent block—an Illinois Department of Public Health piggyback pharmaceutical warehouse order and a Seminole County, Florida procurement for Naloxone and drug deactivation systems—do not involve nafcillin sodium anhydrous. State and local health departments and counties do solicit pharmaceutical products through cooperative purchasing vehicles and competitive bid processes, typically bundling multiple drugs and medical supplies in single awards to reduce administrative overhead and leverage volume pricing. When pharmaceutical procurement does occur at state and local level, it flows through established warehouse and distribution networks, often via MMCAP or similar consortiums that allow multiple jurisdictions to piggyback on framework agreements.

The geographic footprint of state and local pharmaceutical procurement spans multiple states, with documented recent activity in Illinois and Florida. The Illinois Department of Public Health awarded a piggyback contract to Chartwell Rx LLC on August 28, 2026, for antibiotic tablets (Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg) valued at $2,999,999.11 over 12 months with two renewal options; the award followed an Invitation for Bid process and required electronic submission through the state's procurement portal. Seminole County issued an IFB on June 30, 2026, for 1,900 units of Naloxone and 800 drug deactivation systems annually with quarterly deliveries and a two-year initial term plus one-year renewal option. Neither opportunity directly involves nafcillin sodium anhydrous, and the code does not appear to see active state and local procurement volume at present.
