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 1-Bromo-4-(1,1-difluoropropyl)benzene (CAS 162783-79-1), a certified reference material (molecular formula C9H9BrF2, MW 235.07 g/mol) for analytical method development and quality control.
1-Bromo-4-(1,1-difluoropropyl)benzene (C9H9BrF2) contains fluorine/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), 1-Bromo-4-(1,1-difluoropropyl)benzene 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.
