Chemical Structure
Description
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.
2-(4-Isopropylphenyl)-6,8-dimethylquinoline-4-carbonyl chloride (CAS 1160262-70-3), molecular formula C21H20ClNO and molecular weight 337.84 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Isopropylphenyl)-6,8-dimethylquinoline-4-carbonyl chloride (C21H20ClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(4-Isopropylphenyl)-6,8-dimethylquinoline-4-carbonyl chloride 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.
