Chemical Structure
Description
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.
CATO supplies 2-Amino-6-tert-butyl-N-(2,4-dimethoxyphenyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (CAS 587851-01-2), a certified reference material (molecular formula C21H28N2O3S, MW 388.52 g/mol) for analytical method development and quality control.
2-Amino-6-tert-butyl-N-(2,4-dimethoxyphenyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (C21H28N2O3S) contains a steroid core, 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.
