Chemical Structure
Description
CATO supplies 2,3-dichloro-4-methyl-benzaldehyde (CAS 170879-71-7), a certified reference material (molecular formula C8H12Cl2O, MW 195.09 g/mol) for analytical method development and quality control.
The molecular framework of 2,3-dichloro-4-methyl-benzaldehyde (C8H12Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,3-dichloro-4-methyl-benzaldehyde 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.
