Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-2-methylaniline hydrochloride.
3-Ethyl-2-methylaniline hydrochloride (CAS 1201943-76-1) is a high-purity analytical reference standard with the molecular formula C9H13NHCl and a molecular weight of 171.67 g/mol.
Based on its molecular formula C9H13NHCl, 3-Ethyl-2-methylaniline hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 171.67 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.
CATO manufactures 3-Ethyl-2-methylaniline hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
