Chemical Structure
Description
7-chloro-1-methyl-1H-1,3-benzodiazole-2-carbaldehyde (CAS 1344062-76-5) is a high-purity analytical reference standard with the molecular formula C9H15ClN2O and a molecular weight of 202.68 g/mol.
The molecular framework of 7-chloro-1-methyl-1H-1,3-benzodiazole-2-carbaldehyde (C9H15ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 7-chloro-1-methyl-1H-1,3-benzodiazole-2-carbaldehyde 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.
