Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Bromo-3-difluoromethoxy-2-fluoro-4-nitrobenzene (CAS 1807196-14-0), molecular formula C7H3BrF3NO3 and molecular weight 286.00 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-3-difluoromethoxy-2-fluoro-4-nitrobenzene (C7H3BrF3NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 1-Bromo-3-difluoromethoxy-2-fluoro-4-nitrobenzene 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.
