Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Bromo-2,6-difluorophenoxy)-2,2-difluoroacetic acid.
CATO supplies 2-(4-Bromo-2,6-difluorophenoxy)-2,2-difluoroacetic acid (CAS 2137823-73-3), a certified reference material (molecular formula C8H3BrF4O3, MW 303.01 g/mol) for analytical method development and quality control.
2-(4-Bromo-2,6-difluorophenoxy)-2,2-difluoroacetic acid (C8H3BrF4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-(4-Bromo-2,6-difluorophenoxy)-2,2-difluoroacetic acid 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.
