UNSPSC 51283423: Oxetacillin

This classification denotes a penicillin antibiotic with the molecular formula C19H23N3O5S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 47UDJ8GA54, chemically known as (2s,5r,6r)-6-((r)-(4-(p-hydroxyphenyl)-2,2-dimethyl-5-oxo-1-imidazolidinyl)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid but more generally known as oxetacillin, which bears US NIH Compound Identifier 6367080.

UNSPSC 51283423 Oxetacillin, a Commodity code, nominally names a specific antibiotic but shows little relevant recent activity in state and local procurement. The code's recent solicitation history reveals a significant mismatch between the code name and actual buying patterns. Instead of oxetacillin-specific procurement, state and local bodies are soliciting broader pharmaceutical categories: Seminole County, Florida is procuring naloxone and drug deactivation systems through competitive bidding; the City of Tampa is purchasing medical and first aid supplies for emergency response; the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) is sourcing generic multi-source pharmaceuticals and over-the-counter products through an RFP; and the Texas Health and Human Services Commission is exploring direct-to-manufacturer prescription programs via an RFI. The issuing bodies span county health departments, municipal fire and rescue operations, state procurement offices, and cooperative purchasing alliances serving multiple jurisdictions. None of these recent solicitations specifically target oxetacillin or narrow-spectrum penicillin products, suggesting the code may be tagged inconsistently or infrequently in state and local procurement systems.

Recent activity concentrates in Florida, Texas, Minnesota, and Oregon as participants in multi-state cooperative agreements, with no standout repeat buyers at the commodity level. The City of Tampa's IFB 26P00145 for medical and first aid supplies, due March 13, 2026, budgeted $700,000 and carried a 5 percent bid discount for certified Small Local Business Enterprises. Seminole County's IFB 60459723LAS for naloxone and drug deactivation systems, posted June 30, 2026 with response due July 26, 2023, sought 1,900 units of naloxone and 800 safe drug deactivation units annually with quarterly deliveries. MMCAP's RFP S1070000015802 for generic multi-source pharmaceuticals, due March 26, 2026, requires vendors to work through three authorized wholesalers and conform to cGMP and Drug Supply Chain Security Act standards. The Texas HHS RFI HHS0017013, posted April 3, 2026, is exploratory market intelligence rather than a binding procurement. Given the code's narrow definition and the absence of oxetacillin-specific solicitations, firms should verify their product alignment before pursuing this code as a primary pursuit driver.
