Description
CATO supplies 1-Chloro-3,5-Bis-(4-chlorobenzoyl)-2-deoxy-D-ribofuranose (CAS 21740-23-8), a certified reference material (molecular formula C19H15Cl3O6, MW 445.68 g/mol) for analytical method development and quality control.
1-Chloro-3,5-Bis-(4-chlorobenzoyl)-2-deoxy-D-ribofuranose (C19H15Cl3O6) 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.
As a certified reference material (CRM), 1-Chloro-3,5-Bis-(4-chlorobenzoyl)-2-deoxy-D-ribofuranose 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.
