Description
CATO manufactures 4-Bromo-3',3''-difluorotrityl alcohol 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.
CATO supplies 4-Bromo-3',3''-difluorotrityl alcohol (CAS 845790-81-0), a certified reference material (molecular formula C19H13BrF2O, MW 375.21 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 4-Bromo-3',3''-difluorotrityl alcohol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 375.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
