Description
CATO manufactures Ethyl 3,4-difluoro-2-nitrobenzoate 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.
Ethyl 3,4-difluoro-2-nitrobenzoate (CAS 1806289-59-7) is a high-purity analytical reference standard with the molecular formula C9H7F2NO4 and a molecular weight of 231.15 g/mol.
Ethyl 3,4-difluoro-2-nitrobenzoate (C9H7F2NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
