UNSPSC 51342403: Nelfinavir mesilate or mesylate

This classification denotes a protease inhibitor with the molecular formula C32H45N3O4S.CH4O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 98D603VP8V, chemically known as (3s,4as,8as)-n-tert-butyl-2-((2r,3r)-3-(3,2-cresotamido)-2-hydroxy-4-(phenylthio)butyl)decahydro-3-isoquinolinecarboxamide monomethanesulfonate (salt), but more generally known as nelfinavir mesylate, which bears US NIH Compound Identifier 64142.

UNSPSC 51342403 Nelfinavir mesilate or mesylate is a Commodity code for a specific antiretroviral pharmaceutical product, but the recent state and local opportunities tagged under this code do not align with its nominal scope. The Illinois Department of Public Health's August 2026 piggyback pharmaceutical warehouse award through the MMCAP Infuse consortium supplied Doxycycline Hyclate and Ciprofloxacin Hydrochloride—antibiotics used for bacterial infections, not HIV antiretrovirals. Seminole County, Florida's June 2026 IFB for Naloxone and Safe Drug Deactivation Systems solicited opioid-reversal and drug-disposal products unrelated to the code's stated pharmaceutical. State and local procurement offices appear to apply this code inconsistently or as a fallback classification for bundled pharmaceutical purchases, rather than as a targeted procurement for nelfinavir specifically.

The mismatch between the code's definition and the actual work being solicited suggests limited focused activity under UNSPSC 51342403 in state and local procurement. The two most recent opportunities—one an already-awarded IFB through a cooperative purchasing vehicle and one a community health naloxone procurement—involve different pharmaceutical categories entirely. Buyers include state health departments and county health authorities with periodic wholesale pharmaceutical needs. Without current open solicitations for nelfinavir mesilate itself, the code does not present a clear procurement opportunity worth active pursuit at this time.
