Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-4-(bromomethyl)-2,3-difluorobenzene.
1-Bromo-4-(bromomethyl)-2,3-difluorobenzene (CAS 162744-56-1), molecular formula C7H4Br2F2 and molecular weight 285.91 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-4-(bromomethyl)-2,3-difluorobenzene (C7H4Br2F2) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 1-Bromo-4-(bromomethyl)-2,3-difluorobenzene 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.
