[Asp28]-Thymalfasin CAS CATO-C4X-189817

Description

Compared with other compounds in its class, the molecular weight of 3019.30 g/mol gives [Asp28]-Thymalfasin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[Asp28]-Thymalfasin (CAS CATO-C4X-189817), molecular formula C129H214N32O56 and molecular weight 3019.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C129H214N32O56, [Asp28]-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 3019.30 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.

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

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.
