Chemical Structure

2-Methyl-9,10-bis(phenylethynyl)anthracene CAS 51580-23-5 chemical structure

Description

As a certified reference material (CRM), 2-Methyl-9,10-bis(phenylethynyl)anthracene 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.

2-Methyl-9,10-bis(phenylethynyl)anthracene (CAS 51580-23-5), molecular formula C31H20 and molecular weight 392.49 g/mol, is a CATO reference standard with documented purity and traceability.

2-Methyl-9,10-bis(phenylethynyl)anthracene (C31H20) 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 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.
