Ethyl 2-acetamido-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate CAS 76981-73-2

Description

Ethyl 2-acetamido-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 76981-73-2) is a high-purity analytical reference standard with the molecular formula C14H19NO3S and a molecular weight of 281.37 g/mol.

The molecular framework of Ethyl 2-acetamido-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C14H19NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
