Chemical Structure

Benzo(G,H,I)Perylene CAS 191-24-2 chemical structure

Description

The occurrence of Benzo(G,H,I)Perylene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Benzo(G,H,I)Perylene (CAS 191-24-2) is a high-purity analytical reference standard with the molecular formula C22H12 and a molecular weight of 276.33 g/mol.

Benzo(G,H,I)Perylene (C22H12) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Benzo(G,H,I)Perylene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
