Description
As a certified reference material (CRM), 2-Methyl-5-(trifluoromethoxy)benzyl bromide 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.
2-Methyl-5-(trifluoromethoxy)benzyl bromide (CAS 1261573-60-7) is a high-purity analytical reference standard with the molecular formula C9H8BrF3O and a molecular weight of 269.06 g/mol.
The molecular framework of 2-Methyl-5-(trifluoromethoxy)benzyl bromide (C9H8BrF3O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
