Chemical Structure
Description
The molecular framework of 4,5-Dichloro-N1-methylbenzene-1,2-diamine (C7H8Cl2N2) 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).
4,5-Dichloro-N1-methylbenzene-1,2-diamine (CAS 42450-33-9) is a high-purity analytical reference standard with the molecular formula C7H8Cl2N2 and a molecular weight of 191.06 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
