Chemical Structure
Description
The occurrence of 2-Bromo-5-methylbenzotrifluoride is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromo-5-methylbenzotrifluoride (CAS 261952-20-9), a certified reference material (molecular formula C8H6BrF3, MW 239.03 g/mol) for analytical method development and quality control.
Owing to fluorine/bromine substitution, an aromatic ring system, 2-Bromo-5-methylbenzotrifluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-5-methylbenzotrifluoride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
