Chemical Structure
Description
The occurrence of 624-60-2 Ethyl(methyl)ammonium chloride Ethanamine, N-methyl-, hydrochloride (1:1) Ethanamine, N-methyl-, hydrochloride EINECS 210-854-8 Ethylamine, N-methyl-, hydrochloride Ethylmethylamine hydrochloride N-Methylethylamine hydrochloride Methylethylammonium chloride NSC 7301 is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
624-60-2 Ethyl(methyl)ammonium chloride Ethanamine, N-methyl-, hydrochloride (1:1) Ethanamine, N-methyl-, hydrochloride EINECS 210-854-8 Ethylamine, N-methyl-, hydrochloride Ethylmethylamine hydrochloride N-Methylethylamine hydrochloride Methylethylammonium chloride NSC 7301 (CAS 624-60-2), molecular formula C3H9NHCl and molecular weight 95.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C3H9NHCl, 624-60-2 Ethyl(methyl)ammonium chloride Ethanamine, N-methyl-, hydrochloride (1:1) Ethanamine, N-methyl-, hydrochloride EINECS 210-854-8 Ethylamine, N-methyl-, hydrochloride Ethylmethylamine hydrochloride N-Methylethylamine hydrochloride Methylethylammonium chloride NSC 7301 contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 95.57 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.
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.
