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 5-Bromo-1-chloro-2-(propan-2-yloxy)-3-propoxybenzene (CAS 1881293-99-7), a certified reference material (molecular formula C12H16BrClO2, MW 307.61 g/mol) for analytical method development and quality control.
5-Bromo-1-chloro-2-(propan-2-yloxy)-3-propoxybenzene (C12H16BrClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 5-Bromo-1-chloro-2-(propan-2-yloxy)-3-propoxybenzene 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.
