UNSPSC 51201820: Thymopentin

This classification denotes an immunostimulant with the molecular formula C30H49N9O9, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier O3Y80ZF13F, chemically known as l-tyrosine, n-(n-(n-(n(sup 2)-l-arginyl-l-lysyl)-l-alpha-aspartyl)-l-valyl)- but generally known as thymopentin, which bears US NIH Compound Identifier 50587. European Medicines Agency schedules Thymopentin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10993MIG.

UNSPSC 51201820 Thymopentin is a Commodity code for a thymic peptide immunostimulant, but the only recent state and local opportunity tagged to this code is a sole source procurement notice for Yellow Fever Vaccine — a product outside the code's nominal scope. The mismatch suggests either a cataloging error or that the code has seen minimal recent procurement activity aligned with its actual definition. State and local health departments appear to be the primary issuing body for immunological products in this family, though the single available record provides limited visibility into the breadth of agencies or the typical scale of purchases under this code.

The Mississippi State Department of Health posted a sole source notice on July 13, 2026 for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objections due August 3, 2026. The notice invites challenges to the sole source classification and reserves the right to conduct a competitive solicitation if alternative suppliers can be demonstrated. Quantity, contract value, and term were not disclosed. No other recent opportunities under UNSPSC 51201820 are visible in the record; activity in this Commodity code appears sparse relative to broader vaccine and immunological-product procurement.
