Description
CATO supplies 2-Chloro-1,3-bis(3,4-dimethoxyphenyl)propane-1,3-dione (CAS 832737-96-9), a certified reference material (molecular formula C19H19ClO6, MW 378.80 g/mol) for analytical method development and quality control.
2-Chloro-1,3-bis(3,4-dimethoxyphenyl)propane-1,3-dione (C19H19ClO6) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Chloro-1,3-bis(3,4-dimethoxyphenyl)propane-1,3-dione 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.
