Chemical Structure

9-Methylphenanthrene CAS 883-20-5 chemical structure

Description

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.

9-Methylphenanthrene (CAS 883-20-5), molecular formula C15H12 and molecular weight 192.26 g/mol, is a CATO reference standard with documented purity and traceability.

9-Methylphenanthrene (C15H12) 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).

As a certified reference material (CRM), 9-Methylphenanthrene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
