Description

Compared with other compounds in its class, the molecular weight of 356.52 g/mol gives 2-Amino-6-(tert-pentyl)-N-(o-tolyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Amino-6-(tert-pentyl)-N-(o-tolyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (CAS 667436-31-9), molecular formula C21H28N2OS and molecular weight 356.52 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Amino-6-(tert-pentyl)-N-(o-tolyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (C21H28N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
