Chemical Structure
Description
(7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(2-methoxyphenyl)methanone (CAS 175136-41-1) is a high-purity analytical reference standard with the molecular formula C16H13BrO4 and a molecular weight of 349.18 g/mol.
(7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(2-methoxyphenyl)methanone (C16H13BrO4) contains a flavonoid core, a hydroxyl group, an ether linkage, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (7-Bromo-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)(2-methoxyphenyl)methanone 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.
