Chemical Structure
Description
The molecular framework of (2,4-Dichlorophenyl)hydrazine (C6H6Cl2N2) 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).
(2,4-Dichlorophenyl)hydrazine (CAS 13123-92-7) is a high-purity analytical reference standard with the molecular formula C6H6Cl2N2 and a molecular weight of 177.03 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (2,4-Dichlorophenyl)hydrazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
