(5E)-2-Mercapto-5-[(5-methoxy-1H-indol-3-yl)-methylene]-3-phenyl-3,5-dihydro-4H-imidazol-4-one CAS 1142201-48-6

Description

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (5E)-2-Mercapto-5-[(5-methoxy-1H-indol-3-yl)-methylene]-3-phenyl-3,5-dihydro-4H-imidazol-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies (5E)-2-Mercapto-5-[(5-methoxy-1H-indol-3-yl)-methylene]-3-phenyl-3,5-dihydro-4H-imidazol-4-one (CAS 1142201-48-6), a certified reference material (molecular formula C19H15N3O2S, MW 349.41 g/mol) for analytical method development and quality control.

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.
