Description
CATO supplies Methyl 2-(2-cyano-3-(4-(diethylamino)phenyl)acrylamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 379714-54-2), a certified reference material (molecular formula C24H27N3O3S, MW 437.55 g/mol) for analytical method development and quality control.
Structurally, Methyl 2-(2-cyano-3-(4-(diethylamino)phenyl)acrylamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C24H27N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 437.55 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
