Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-N-(3-methoxyphenyl)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide.
CATO supplies 2-Amino-N-(3-methoxyphenyl)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (CAS 725221-40-9), a certified reference material (molecular formula C17H20N2O2S, MW 316.42 g/mol) for analytical method development and quality control.
The molecular framework of 2-Amino-N-(3-methoxyphenyl)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (C17H20N2O2S) is characterized by a steroid core, an amide group, a sulfone group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 2-Amino-N-(3-methoxyphenyl)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
