Chemical Structure

6,8-Dimethyl-1H-imidazo[4,5-h]quinoline CAS 137654-49-0 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.

CATO supplies 6,8-Dimethyl-1H-imidazo[4,5-h]quinoline (CAS 137654-49-0), a certified reference material (molecular formula C12H11N3, MW 197.24 g/mol) for analytical method development and quality control.

6,8-Dimethyl-1H-imidazo[4,5-h]quinoline (C12H11N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
