Ethyl 2-benzamido-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate CAS 63274-52-2 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 Ethyl 2-benzamido-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate.

CATO supplies Ethyl 2-benzamido-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (CAS 63274-52-2), a certified reference material (molecular formula C19H21NO3S, MW 343.44 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-benzamido-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (C19H21NO3S) 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. 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.

CATO manufactures Ethyl 2-benzamido-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate 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.
