4-tert-Butyl-3,4-dimethylbenzophenone CAS 951884-25-6

Description

The occurrence of 4-tert-Butyl-3,4-dimethylbenzophenone is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-tert-Butyl-3,4-dimethylbenzophenone (CAS 951884-25-6), molecular formula C19H22O and molecular weight 266.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-tert-Butyl-3,4-dimethylbenzophenone (C19H22O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-tert-Butyl-3,4-dimethylbenzophenone 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.
