Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-Bromo-2,4-difluoro-3-(trimethylsilyl)benzaldehyde (CAS 651326-71-5), a certified reference material (molecular formula C10H11BrF2OSi, MW 293.18 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 6-Bromo-2,4-difluoro-3-(trimethylsilyl)benzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 6-Bromo-2,4-difluoro-3-(trimethylsilyl)benzaldehyde 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.
