7,8-Dimethyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride CAS 1160261-34-6

Description

The occurrence of 7,8-Dimethyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7,8-Dimethyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride (CAS 1160261-34-6), molecular formula C19H16ClNO and molecular weight 309.79 g/mol, is a CATO reference standard with documented purity and traceability.

7,8-Dimethyl-2-(4-methylphenyl)quinoline-4-carbonyl chloride (C19H16ClNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 7,8-Dimethyl-2-(4-methylphenyl)quinoline-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.
