Description
Compared with other compounds in its class, the molecular weight of 237.04 g/mol gives 2-Bromo-1-difluoromethoxy-4-methyl-benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-1-difluoromethoxy-4-methyl-benzene (CAS 954235-93-9), molecular formula C8H7BrF2O and molecular weight 237.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-1-difluoromethoxy-4-methyl-benzene (C8H7BrF2O) 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.
