Chemical Structure

3-Methylcholanthrene CAS 56-49-5 chemical structure

Description

The occurrence of 3-Methylcholanthrene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methylcholanthrene (CAS 56-49-5) is a high-purity analytical reference standard with the molecular formula C21H16 and a molecular weight of 268.35 g/mol.

3-Methylcholanthrene (C21H16) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
