Chemical Structure

1H-Cyclopenta[b]imidazo[4,5-g]indole CAS 105790-42-9 chemical structure

Description

1H-Cyclopenta[b]imidazo[4,5-g]indole (CAS 105790-42-9) is a high-purity analytical reference standard with the molecular formula C12H7N3 and a molecular weight of 193.20 g/mol.

The molecular framework of 1H-Cyclopenta[b]imidazo[4,5-g]indole (C12H7N3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
