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.
1-(3-Chloropyridin-4-yl)-N-methylmethanamine (CAS 823189-17-9) is a high-purity analytical reference standard with the molecular formula C7H9ClN2 and a molecular weight of 156.61 g/mol.
The molecular framework of 1-(3-Chloropyridin-4-yl)-N-methylmethanamine (C7H9ClN2) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-(3-Chloropyridin-4-yl)-N-methylmethanamine 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.
