UNSPSC 51282138: Sulbenicillin disodium

This classification denotes a penicillin antibiotic with the molecular formula C16H16N2O7S2.2Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 29SO9LIM1Q, chemically known as d-(-)-.alpha.-sulfobenzylpenicillin sodium salt, but more generally known as sulbenicillin disodium, which bears US NIH Compound Identifier 134931. European Medicines Agency schedules sulbenicillin disodium or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15423MIG.

Most nations, for tariff purposes, schedule sulbenicillin disodium under HS 29411090. SMILES: CC1([C@@H](N2[C@H](S1)[C@@H](C2=O)NC(=O)[C@@H](C3CCCCC3)S(=O)(=O)[O-])C(=O)[O-])C.[NA+].[NA+].

UNSPSC 51282138 Sulbenicillin disodium is a Commodity code that nominally covers a specific antibiotic pharmaceutical product, but the recent state and local opportunities posted under this code show minimal alignment with the code's stated scope. The two most recent opportunities on record involve unrelated pharmaceutical procurements: one was a completed piggyback award through Illinois Department of Public Health for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets, and the other is a Seminole County, Florida procurement for Naloxone and drug deactivation systems. Neither solicitation addresses Sulbenicillin disodium directly, and neither represents active open bidding windows—the Illinois award closed in September 2026, and the Seminole County bid window closed in July 2023.

State and local procurement activity under this code appears limited and misaligned with its nominal scope. The issuing bodies span a state health department and a county government, with geographic presence in Illinois and Florida based on the available record. Given the sparse and off-target nature of recent postings, firms pursuing work in antibiotic pharmaceuticals or similar specialty drugs should verify code assignment with procurement offices before investing in responses, as the existing opportunities suggest either sporadic use of this code or systematic miscoding by issuing agencies.
