3,4-Dimethyl-3-(2,3-dimethylphenyl)propiophenone CAS 898792-83-1

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 3,4-Dimethyl-3-(2,3-dimethylphenyl)propiophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

3,4-Dimethyl-3-(2,3-dimethylphenyl)propiophenone (CAS 898792-83-1), molecular formula C19H22O and molecular weight 266.38 g/mol, is a CATO reference standard with documented purity and traceability.

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), 3,4-Dimethyl-3-(2,3-dimethylphenyl)propiophenone 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.
