About Thymalfasin

Vaqora Chemicals supplies Thymalfasin, a high-purity reference standard of Thymosin registered under CAS number 69521-94-4. The compound has the formula C129H215N33O55, corresponding to a molecular weight of 3108.3 g/mol. Alternative names: Thymosin α1 and Thymosin alpha1.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

As a reference sample of Thymosin, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
