Chemical Structure

5-Chlorobenzo[b]thiophen-3-amine CAS 1378658-41-3 chemical structure

Description

The occurrence of 5-Chlorobenzo[b]thiophen-3-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Chlorobenzo[b]thiophen-3-amine (CAS 1378658-41-3), a certified reference material (molecular formula C8H6ClNS, MW 183.66 g/mol) for analytical method development and quality control.

Structurally, 5-Chlorobenzo[b]thiophen-3-amine (C8H6ClNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 183.66 g/mol, it falls into the medium-molecular-weight range. 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.
