Compared with other compounds in its class, the molecular weight of 268.16 g/mol gives Chlorpromazine Impurity 6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chlorpromazine Impurity 6 (CAS 1730-46-7), a certified reference material (molecular formula C12H7Cl2NS, MW 268.16 g/mol) for analytical method development and quality control.
The molecular framework of Chlorpromazine Impurity 6 (C12H7Cl2NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Chlorpromazine Impurity 6 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.
