Description
CATO manufactures 1-Bromo-2-chloro-5-methyl-3-nitrobenzene 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 1-Bromo-2-chloro-5-methyl-3-nitrobenzene (CAS 89642-18-2), a certified reference material (molecular formula C7H5BrClNO2, MW 250.48 g/mol) for analytical method development and quality control.
1-Bromo-2-chloro-5-methyl-3-nitrobenzene (C7H5BrClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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.
