Chemical Structure
Description
CATO supplies 4-Bromo-2,2-difluoro-1,3-benzodioxole (CAS 144584-66-7), a certified reference material (molecular formula C7H9BrF2O2, MW 243.05 g/mol) for analytical method development and quality control.
4-Bromo-2,2-difluoro-1,3-benzodioxole (C7H9BrF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-Bromo-2,2-difluoro-1,3-benzodioxole 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.
