Chemical Structure

2-Methylthiophen-3-amine hydrochloride CAS 24029-98-9 chemical structure

Description

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.

2-Methylthiophen-3-amine hydrochloride (CAS 24029-98-9) is a high-purity analytical reference standard with the molecular formula C5H7NSHCl and a molecular weight of 149.64 g/mol.

Based on its molecular formula C5H7NSHCl, 2-Methylthiophen-3-amine hydrochloride contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 149.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
