Chemical Structure

Ethyl 4,5,6,7-tetrahydrobenzo[c]thiophene-1-carboxylate CAS 96986-78-6 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 4,5,6,7-tetrahydrobenzo[c]thiophene-1-carboxylate.

CATO supplies Ethyl 4,5,6,7-tetrahydrobenzo[c]thiophene-1-carboxylate (CAS 96986-78-6), a certified reference material (molecular formula C11H14O2S, MW 210.29 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 4,5,6,7-tetrahydrobenzo[c]thiophene-1-carboxylate (C11H14O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
