Chemical Structure

4-Chloro-6-methylquinoline CAS 18436-71-0 chemical structure

Description

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.

4-Chloro-6-methylquinoline (CAS 18436-71-0), molecular formula C10H18ClN and molecular weight 187.71 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H18ClN, 4-Chloro-6-methylquinoline contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 187.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
