Chemical Structure
Description
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 supplies 6-Bromo-4-chloro-2,3-difluorobenzaldehyde (CAS 2514941-95-6), a certified reference material (molecular formula C7H2BrClF2O, MW 255.44 g/mol) for analytical method development and quality control.
6-Bromo-4-chloro-2,3-difluorobenzaldehyde (C7H2BrClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
As a certified reference material (CRM), 6-Bromo-4-chloro-2,3-difluorobenzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
