Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.01 g/mol gives 3,4-Dichloro-5-nitroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,4-Dichloro-5-nitroaniline (CAS 1806348-70-8) is a high-purity analytical reference standard with the molecular formula C6H4Cl2N2O2 and a molecular weight of 207.01 g/mol.
3,4-Dichloro-5-nitroaniline (C6H4Cl2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 3,4-Dichloro-5-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.
