Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
((2-Bromothiazol-4-yl)difluoromethyl)phosphonic acid (CAS 2694728-11-3) is a high-purity analytical reference standard with the molecular formula C4H3BrF2NO3PS and a molecular weight of 294.01 g/mol.
((2-Bromothiazol-4-yl)difluoromethyl)phosphonic acid (C4H3BrF2NO3PS) contains an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures ((2-Bromothiazol-4-yl)difluoromethyl)phosphonic 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.
