Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Bromomethyl)-2,5-difluoro-4-methoxybenzene (CAS 873373-81-0), molecular formula C8H7BrF2O and molecular weight 237.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Bromomethyl)-2,5-difluoro-4-methoxybenzene (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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1-(Bromomethyl)-2,5-difluoro-4-methoxybenzene 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.
