2,4-Dichloro-6-methylquinoline-3-carbonitrile CAS 749865-98-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dichloro-6-methylquinoline-3-carbonitrile.

2,4-Dichloro-6-methylquinoline-3-carbonitrile (CAS 749865-98-3), molecular formula C11H6Cl2N2 and molecular weight 237.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,4-Dichloro-6-methylquinoline-3-carbonitrile (C11H6Cl2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-Dichloro-6-methylquinoline-3-carbonitrile 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.
