Chemical Structure

3-Ethyl-2-methylaniline CAS 857245-39-7 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.

3-Ethyl-2-methylaniline (CAS 857245-39-7), molecular formula C9H13N and molecular weight 135.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H13N, 3-Ethyl-2-methylaniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 135.21 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.

As a certified reference material (CRM), 3-Ethyl-2-methylaniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
