Chemical Structure

2-Methyl-1H-imidazo[4,5-f]isoquinoline CAS 140192-87-6 chemical structure

Description

The molecular framework of 2-Methyl-1H-imidazo[4,5-f]isoquinoline (C11H9N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

2-Methyl-1H-imidazo[4,5-f]isoquinoline (CAS 140192-87-6) is a high-purity analytical reference standard with the molecular formula C11H9N3 and a molecular weight of 183.21 g/mol.

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.

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.
