Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl 4-bromo-7-methoxybenzo[d][1,3]dioxole-5-carboxylate (CAS 81474-46-6), a certified reference material (molecular formula C10H9BrO5, MW 289.08 g/mol) for analytical method development and quality control.
Methyl 4-bromo-7-methoxybenzo[d][1,3]dioxole-5-carboxylate (C10H9BrO5) 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.
CATO manufactures Methyl 4-bromo-7-methoxybenzo[d][1,3]dioxole-5-carboxylate 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.
