Chemical Structure
Description
4-Amino-2,6-dichlorobenzonitrile (CAS 6575-18-4) is a high-purity analytical reference standard with the molecular formula C7H4Cl2N2 and a molecular weight of 187.03 g/mol.
The molecular framework of 4-Amino-2,6-dichlorobenzonitrile (C7H4Cl2N2) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 4-Amino-2,6-dichlorobenzonitrile 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.
