Chemical Structure

3-Methyl-1-benzothiophen-5-amine CAS 19404-20-7 chemical structure

Description

3-Methyl-1-benzothiophen-5-amine (CAS 19404-20-7) is a high-purity analytical reference standard with the molecular formula C9H9NS and a molecular weight of 163.24 g/mol.

3-Methyl-1-benzothiophen-5-amine (C9H9NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
