UNSPSC 51203500: Immunosupressant aziridines

This classification denotes saturated azacyclopropane compounds, called aziridines, that reduce a human host's humoral and/or cell-mediated defense mechanisms against deviant native cells, foreign organisms, or foreign substances (the human immune response and system thereof), thus the term IMMUNOSUPPRESSANT AZIRIDINES.

UNSPSC 51203500 Immunosuppressant aziridines is a Class code that in recent state and local activity covers pharmaceutical procurement through piggyback and direct-purchase contracts for specific drug products. The recent opportunities posted under this code do not align with the code's nominal scope—the opportunities target antibiotic tablets (Doxycycline Hyclate and Ciprofloxacin Hydrochloride), naloxone, and drug deactivation systems rather than immunosuppressant aziridines. State and local health departments and county public health authorities are the primary issuing bodies, procuring pharmaceuticals and related medical supplies through both cooperative purchasing vehicles (MMCAP Infuse consortium piggyback contracts) and direct IFB processes. The code shows limited and mislabeled recent activity, suggesting either inconsistent classification in state and local procurement systems or minimal current demand for the specific pharmaceutical class the code nominates.

The Illinois Department of Public Health and Seminole County, Florida represent the geographic spread in the recent record. The Illinois DPH awarded a piggyback pharmaceutical warehouse contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026 (Solicitation 26482DPHPREPDB53392, award $2,999,999.11 over 12 months plus two renewal years) for Doxycycline Hyclate and Ciprofloxacin tablets; the award is completed and closed. Seminole County issued an IFB (IFB60459723LAS, posted June 30, 2026, due July 26, 2023) for 1,900 units of naloxone and 800 drug deactivation systems annually with quarterly deliveries, E-Verify compliance, and workers' compensation and liability insurance requirements; the due date stamp appears inconsistent with the posting date and may reflect data entry error. The code shows little relevant recent activity aligned to its stated scope.
