Description
Compared with other compounds in its class, the molecular weight of 309.94 g/mol gives 3,5-Dibromo-4-Hydroxybenzoic Acid Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,5-Dibromo-4-Hydroxybenzoic Acid Methyl Ester (CAS 41727-47-3), molecular formula C8H6Br2O3 and molecular weight 309.94 g/mol, is a CATO reference standard with documented purity and traceability.
3,5-Dibromo-4-Hydroxybenzoic Acid Methyl Ester (C8H6Br2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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 3,5-Dibromo-4-Hydroxybenzoic Acid Methyl Ester 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.
