UNSPSC 51283506: Cloxacillin benzathine

This classification denotes a penicillin antibiotic with the molecular formula 2C19H18ClN3O5S.C16H20N2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier AC79L7PV2G, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 6-(((3-(2-chlorophenyl)-5-methyl-4-isoxazolyl)carbonyl)amino)-3,3-dimethyl-7-oxo-, (2s-(2.alpha.,5.alpha.,6.beta.))-, compd. with n,n'-bis(phenylmethyl)-1,2-ethanediamine (2:1), but more generally known as cloxacillin benzathine, which bears US NIH Compound Identifier 64706.

UNSPSC 51283506 Cloxacillin benzathine is a Commodity code, but the recent state and local opportunities solicited under it bear minimal relationship to the code's nominal pharmaceutical product. The code shows no recent activity aligned with cloxacillin benzathine procurement; instead, the tagged opportunities reflect broader pharmaceutical, medical supply, and pharmacy benefit program solicitations that do not target this specific antibiotic agent. State and local governments soliciting under this code are addressing emergency medical supplies, naloxone distribution, generic pharmaceutical frameworks, and therapeutic pharmacy initiatives—categories distinct from cloxacillin benzathine acquisition.

Recent opportunities span Florida, Texas, Minnesota, and Oregon. The Seminole County, Florida IFB (60459723LAS) sought naloxone and drug deactivation systems, not antibiotics, with an electronic bid deadline of July 26, 2023. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration, issued an RFP for generic multi-source pharmaceuticals and OTC products with a March 26, 2026 proposal deadline, establishing frameworks for authorized wholesaler distribution across state and local facilities. The Texas Health and Human Services Commission posted an RFI on direct-to-manufacturer prescription programs in April 2026. The City of Tampa's March 2026 sealed-bid solicitation for medical and first aid supplies to the Tampa Fire Department Rescue Division, estimated at $700,000, included a small local business enterprise set-aside with a 5 percent bid discount. The issuing-body mix spans county health departments, state HHS agencies, cities, and cooperative purchasing alliances. The code's activity suggests tagging drift or categorization mismatch rather than active cloxacillin benzathine demand at the state and local level.
