Chemical Structure

Bis(3,5-dimethylphenyl)methanone CAS 22679-40-9 chemical structure

Description

CATO supplies Bis(3,5-dimethylphenyl)methanone (CAS 22679-40-9), a certified reference material (molecular formula C17H18O, MW 238.32 g/mol) for analytical method development and quality control.

Structurally, Bis(3,5-dimethylphenyl)methanone (C17H18O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 238.32 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), Bis(3,5-dimethylphenyl)methanone 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.
