Description
As a certified reference material (CRM), 5-Bromo-4-fluoro-2-methoxybenzonitrile 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.
5-Bromo-4-fluoro-2-methoxybenzonitrile (CAS 1379366-31-0), molecular formula C8H5BrFNO and molecular weight 230.03 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-4-fluoro-2-methoxybenzonitrile (C8H5BrFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
