Chemical Structure
Description
CATO supplies 2,3-Dibromo-4-(difluoromethoxy)benzaldehyde (CAS 1803812-87-4), a certified reference material (molecular formula C8H4Br2F2O2, MW 329.92 g/mol) for analytical method development and quality control.
2,3-Dibromo-4-(difluoromethoxy)benzaldehyde (C8H4Br2F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Dibromo-4-(difluoromethoxy)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.
