Chemical Structure
Description
As a certified reference material (CRM), 1-(2,3-Dichlorophenyl)-N-methylmethanamine hydrochloride 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.
1-(2,3-Dichlorophenyl)-N-methylmethanamine hydrochloride (CAS 39959-78-9) is a high-purity analytical reference standard with the molecular formula C8H9Cl2NHCl and a molecular weight of 226.53 g/mol.
The molecular framework of 1-(2,3-Dichlorophenyl)-N-methylmethanamine hydrochloride (C8H9Cl2NHCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
