UNSPSC 51283508: Cloxacillin sodium anhydrous

This classification denotes a penicillin antibiotic C19H17ClN3O5S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier MWQ645MKMF, chemically known as cloxacillin sodium, anhydrous, but more generally known as cloxacillin sodium anhydrous, which bears US NIH Compound Identifier 23675320. Most nations, for tariff and trade purposes, schedule cloxacillin sodium anhydrous under HS 29411090 and SITC 54131. As of Q4 2014, CLOXACILLIN SODIUM ANHYDROUS remains US FDA's Preferred Term for this commodity.

Cloxacillin sodium anhydrous bears US NLM identifiers UMLS ID C2699387 and NCI Concept Code C76222. SMILES: CC1C(C(NO1)C2CCCCC2CL)C(=O)N[C@H]3[C@@H]4N(C3=O)[C@H](C(S4)(C)C)C(=O)[O-].[NA+].

UNSPSC 51283508 Cloxacillin sodium anhydrous, a Commodity code, does not align with the recent state and local procurement activity tagged under it. The four recent opportunities in the dataset soliciting under this code span naloxone and drug deactivation systems (Seminole County, Florida), direct-to-manufacturer prescription programs (Texas Health and Human Services Commission), medical and first aid supplies for fire rescue (City of Tampa), and generic pharmaceuticals and OTC products through a multistate cooperative vehicle (Minnesota Multistate Cooperative Purchasing Alliance / MMCAP). None of these solicitations name cloxacillin sodium anhydrous or antibiotics as a line item or scope requirement. The code shows little relevant recent activity; the tagged opportunities reflect broader pharmaceutical procurement, emergency medical supplies, and pharmacy benefit program administration rather than procurement of this specific antibiotic product.

The issuing bodies include a county health department, a state HHS commission, a municipal fire department, and a multistate cooperative purchasing alliance spanning Minnesota, Oregon, and participating states. Geographic spread across the recent activity covers Florida, Texas, Florida again, and Minnesota / multi-state, with no concentration in any single region. The City of Tampa's medical and first aid supplies bid (IFB, due March 13, 2026, estimated $700,000) and MMCAP's generic pharmaceutical RFP (due March 26, 2026) represent the most concrete procurement vehicles, but neither targets cloxacillin sodium anhydrous specifically. Without evidence of direct demand for this commodity under the code, pursuing opportunities here would require confirming that end-user specifications actually require this product rather than relying on the UNSPSC tagging.
