UNSPSC 51201828: Levamisole phosphate

This classification denotes a biological response modifier and antihelminthic agent with the molecular formula C11H12N2S.H3O4P, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier FIG89N8AZY, chemically known as (s)-2,3,5,6-tetrahydro-6-phenylimidazo(2,1-b)thiazoletriylium phosphate but more generally known as levamisole phosphate, which bears US NIH Compound Identifier 198119. Most nations, for tariff and trade purposes, schedule levamisole phosphate under HS 29349990.

As of Q4 2014, LEVAMISOLE PHOSPHATE remains US FDA's Preferred Term for this commodity. Levamisole phosphate bears US NLM identifiers UMLS ID C0309393 and NCI Concept Code C77331. SMILES: C1CCC(CC1)[C@H]2CN3CCSC3=N2.OP(=O)(O)O.

UNSPSC 51201828 Levamisole phosphate is a Commodity code that in recent state and local procurement activity covers pharmaceutical products for public health use, specifically vaccines and related immunological preparations. State health departments are the primary issuing bodies under this code, procuring supplies for disease prevention and immunization programs that serve public populations. The scope of work reflects direct government procurement of finished pharmaceutical products rather than raw chemical compounds, with state health agencies managing acquisition through both competitive and sole-source mechanisms depending on vendor availability and clinical necessity.

The Mississippi State Department of Health posted a sole-source procurement notice on July 13, 2026, for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objections due August 3, 2026. This represents the only recent activity visible under the code. The notice invites stakeholders to challenge the sole-source designation by demonstrating alternative vendor availability; if substantiated objections are received, the department will conduct a competitive bid process. The procurement does not specify quantity, contract term, or estimated value. Geographic concentration in this code appears limited to Mississippi based on recent posting activity, and state health department procurement of vaccines and immunological products may represent sporadic, need-driven acquisition rather than routine scheduled purchasing.
