Chemical Structure
Description
The occurrence of Ethyl 3,4-bis(benzyloxy)benzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 3,4-bis(benzyloxy)benzoate (CAS 174398-83-5), molecular formula C23H22O4 and molecular weight 362.42 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 3,4-bis(benzyloxy)benzoate (C23H22O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
