[D-Ser9]-Thymalfasin CAS CATO-C4X-189814 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

[D-Ser9]-Thymalfasin (CAS CATO-C4X-189814) is a high-purity analytical reference standard with the molecular formula C129H215N33O55 and a molecular weight of 3108.28 g/mol.

Based on its molecular formula C129H215N33O55, [D-Ser9]-Thymalfasin contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 3108.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
