(S)-3-(4-Mercapto-1-methyl-1H-imidazol-5-yl)-2-(methylamino)propanoic acid CAS 108418-14-0

Description

The occurrence of (S)-3-(4-Mercapto-1-methyl-1H-imidazol-5-yl)-2-(methylamino)propanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-3-(4-Mercapto-1-methyl-1H-imidazol-5-yl)-2-(methylamino)propanoic acid (CAS 108418-14-0), molecular formula C8H13N3O2S and molecular weight 215.27 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-3-(4-Mercapto-1-methyl-1H-imidazol-5-yl)-2-(methylamino)propanoic acid (C8H13N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
