Chemical Structure

Butyl 1-bromo-4-hydroxy-7-phenoxyisoquinoline-3-carboxylate CAS 808115-53-9 chemical structure

Description

Butyl 1-bromo-4-hydroxy-7-phenoxyisoquinoline-3-carboxylate (C20H18BrNO4) contains a flavonoid core, an amide group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies Butyl 1-bromo-4-hydroxy-7-phenoxyisoquinoline-3-carboxylate (CAS 808115-53-9), a certified reference material (molecular formula C20H18BrNO4, MW 416.27 g/mol) for analytical method development and quality control.

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.
