Chemical Structure
Description
As a certified reference material (CRM), 1,3-Dibromo-5-(tert-butyl)-2-methylbenzene 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.
CATO supplies 1,3-Dibromo-5-(tert-butyl)-2-methylbenzene (CAS 108545-81-9), a certified reference material (molecular formula C11H14Br2, MW 306.04 g/mol) for analytical method development and quality control.
Owing to bromine substitution, an aromatic ring system, 1,3-Dibromo-5-(tert-butyl)-2-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.04 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
