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 2-Bromo-4-methyl-1-(pentyloxy)benzene (CAS 1040345-76-3), a certified reference material (molecular formula C12H17BrO, MW 257.17 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-4-methyl-1-(pentyloxy)benzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 257.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-Bromo-4-methyl-1-(pentyloxy)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.
