UNSPSC 51343507: Cidofovir sodium

This classification denotes an antiviral agent with the molecular formula C8H12N3O6P.2Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier M83JB37U61, chemically known as phosphonic acid, ((2-(4-amino-2-oxo-1(2h)-pyrimidinyl)-1-(hydroxymethyl)ethoxy)methyl)-, disodium salt, (s)-, but more generally known as cidofovir sodium, which bears US NIH Compound Identifier 135406. European Medicines Agency schedules cidofovir sodium or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06257MIG.

Most nations, for tariff purposes, schedule cidofovir sodium under HS 29335995. SMILES: C1CN(C(=O)NC1N)C[C@@H](CO)OCP(=O)([O-])[O-].[NA+].[NA+].

UNSPSC 51343507 Cidofovir sodium is a Commodity code for a specific antiviral pharmaceutical product, but the recent state and local opportunities tagged under this code do not reflect procurement of cidofovir itself. Instead, the solicitations posted under the code involve broader pharmaceutical and medical supply distribution — specifically antibiotics (doxycycline and ciprofloxacin) through a statewide cooperative purchasing vehicle, and naloxone plus drug deactivation systems through a county health authority. The mismatch suggests either a cataloging error in how these opportunities were classified or that state and local procurement systems are using this code as a catch-all for pharmaceutical warehouse and emergency medical supply orders. State and local governments appear to be using this code tier to buy pharmaceuticals and medical supplies through cooperative agreements and direct competitive bids, but the actual scope under active solicitation does not align with cidofovir specifically.

Illinois Department of Public Health awarded a piggyback pharmaceutical contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for doxycycline and ciprofloxacin under an IFB process, with a total contract value of $2,999,999.11 over 12 months plus two renewal years. Seminole County, Florida posted an IFB in June 2026 for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries, though the due date listed in the source (July 26, 2023) appears to be a data error. Geographic activity is concentrated in the South and Midwest based on these recent postings, but the cidofovir code shows little relevant recent activity — the opportunities tagged to it are generic pharmaceutical and emergency medical supply purchases that do not target cidofovir specifically.
