4,7-dichloroimidazo[1,5-a]quinoxaline CAS 847900-55-4

Description

Compared with other compounds in its class, the molecular weight of 250.17 g/mol gives 4,7-dichloroimidazo[1,5-a]quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,7-dichloroimidazo[1,5-a]quinoxaline (CAS 847900-55-4) is a high-purity analytical reference standard with the molecular formula C10H17Cl2N3 and a molecular weight of 250.17 g/mol.

The molecular framework of 4,7-dichloroimidazo[1,5-a]quinoxaline (C10H17Cl2N3) is characterized by a nitrile group, chlorine substitution. 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 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.

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.
