7-Chloro-2-(4-methoxyphenyl)-8-methylquinoline-4-carbonyl chloride CAS 1160263-66-0 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.

7-Chloro-2-(4-methoxyphenyl)-8-methylquinoline-4-carbonyl chloride (CAS 1160263-66-0), molecular formula C18H13Cl2NO2 and molecular weight 346.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7-Chloro-2-(4-methoxyphenyl)-8-methylquinoline-4-carbonyl chloride (C18H13Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 346.21 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
