Chemical Structure
Description
The occurrence of Eosin diacetate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Eosin diacetate (CAS 7284-92-6), a certified reference material (molecular formula C24H12Br4O7, MW 731.96 g/mol) for analytical method development and quality control.
Eosin diacetate (C24H12Br4O7) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine 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 Eosin diacetate 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.
