UNSPSC 51282420: Mezlocillin sodium monohydrate

This classification denotes an extended spectrum penicillin antibiotic C21H24N5O8S2.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3CWW8B5904, chemically known as sodium (2s,5r,6r)-3,3-dimethyl-6-((r)-2-(3-(methylsulfonyl)-2-oxo-1-imidazolidinecarboxamido)-2-phenylacetamido)-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylate, monohydrate, but more generally known as mezlocillin sodium monohydrate, which bears US NIH Compound Identifier 23677831.

UNSPSC 51282420 Mezlocillin sodium monohydrate (Commodity) shows minimal alignment between its nominal pharmaceutical code and the state and local opportunities recently tagged to it. The recent solicitations under this code span naloxone and drug deactivation systems, direct-to-manufacturer prescription programs, medical and first aid supplies for emergency response, and generic multi-source pharmaceuticals through cooperative purchasing — none of which center on mezlocillin sodium monohydrate specifically. State and local procurement offices are acquiring these products through diverse issuing bodies: county health departments (Seminole County, Florida), state health and human services commissions (Texas HHS Commission), city fire departments (City of Tampa), and multistate cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance, serving participating state and local facilities across multiple states including Oregon). The scope of work reflects broad pharmaceutical and medical-supply procurement rather than a single active pharmaceutical ingredient.

Recent representative opportunities include Seminole County's IFB for 1,900 units of naloxone and 800 safe drug deactivation systems annually (IFB 60459723LAS, due July 26, 2023), the Texas HHS Commission's Request for Information on direct-to-manufacturer prescription program capabilities (RFI HHS0017013, posted April 3, 2026), the City of Tampa's invitation to bid for 169 line items of medical and first aid supplies for the Fire Department Rescue Division with an estimated contract value of $700,000.00 and a Small Local Business Enterprise set-aside with 5% bid discount (IFB 26P00145, due March 13, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance's RFP for generic multi-source pharmaceuticals and OTC products distributed through authorized wholesalers (RFP S1070000015802, due March 26, 2026). Geographic activity spans Florida, Texas, Minnesota, and Oregon. The mismatch between the code's nominal focus and the actual scope of recent opportunities suggests that this code classification may not reliably identify relevant procurement pipelines for firms targeting specific pharmaceutical products or services.
