Chemical Structure

4-Bromo-N-(4-chlorophenyl)-5-methyl-2-nitroaniline CAS 105520-45-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Bromo-N-(4-chlorophenyl)-5-methyl-2-nitroaniline (CAS 105520-45-4) is a high-purity analytical reference standard with the molecular formula C13H10BrClN2O2 and a molecular weight of 341.59 g/mol.

4-Bromo-N-(4-chlorophenyl)-5-methyl-2-nitroaniline (C13H10BrClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 4-Bromo-N-(4-chlorophenyl)-5-methyl-2-nitroaniline 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.
