UNSPSC 51284611: Imipenem anhydrous

This classification denotes a beta-lactam antibiotic with the molecular formula C12H17N3O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Q20IM7HE75, chemically known as 1-azabicyclo(3.2.0)hept-2-ene-2-carboxylic acid, 6-(1-hydroxyethyl)-3-((2-((iminomethyl)amino)ethyl)thio)-7-oxo-, (5r-(5.alpha.,6.alpha.(r*)))-, but more generally known as imipenem anhydrous, which bears US NIH Compound Identifier 47317.

European Medicines Agency schedules imipenem anhydrous or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08151MIG. Most nations, for tariff purposes, schedule imipenem anhydrous under HS 29419000. SMILES: C[C@H]([C@@H]1[C@H]2CC(=C(N2C1=O)C(=O)O)SCCNC=N)O.

UNSPSC 51284611 Imipenem anhydrous, a Commodity code, nominally covers injectable antibiotic pharmaceutical products. However, the recent state and local opportunities tagged under this code show little activity directly aligned with imipenem procurement. The Illinois Department of Public Health's August 2026 piggyback pharmaceutical warehouse award through MMCAP Infuse to Chartwell Rx LLC supplied Doxycycline Hyclate and Ciprofloxacin Hydrochloride — oral antibiotics unrelated to imipenem — under a $2,999,999.11 contract with a 12-month initial term and two renewal options. A second opportunity posted by Seminole County, Florida in June 2026 sought Naloxone and Safe Drug Deactivation Systems, products wholly outside the imipenem scope. State and local health departments and county health authorities appear to be the primary issuing bodies using this code or related pharmaceutical commodity codes, typically through cooperative purchasing consortia such as MMCAP Infuse rather than as standalone procurements.

The source reflects minimal recent activity under imipenem anhydrous specifically. The two posted opportunities — the Illinois Department of Public Health award (completed, not an open solicitation) and the Seminole County IFB (due July 26, 2023, now closed) — do not represent current purchasing under this code for imipenem. Geographic activity, where present, centers on Illinois and Florida, but the actual commodities being procured diverge significantly from the code's nominal scope. A business development professional evaluating this Commodity code should note the mismatch between the code designation and recent opportunity content, and verify whether imipenem demand flows through alternative code assignments, state-level pharmaceutical contracts, or federal purchasing vehicles rather than through direct state and local procurement channels.
