Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-4-formyl-6-methoxyphenyl 4-chlorobenzoate.
2-Bromo-4-formyl-6-methoxyphenyl 4-chlorobenzoate (CAS 432011-25-1), molecular formula C15H10BrClO4 and molecular weight 369.59 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-4-formyl-6-methoxyphenyl 4-chlorobenzoate (C15H10BrClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
