Chemical Structure
Description
As a certified reference material (CRM), 4-(2,5-Dimethylbenzoyl)phenyl acetate 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.
4-(2,5-Dimethylbenzoyl)phenyl acetate (CAS 303098-84-2) is a high-purity analytical reference standard with the molecular formula C17H16O3 and a molecular weight of 268.31 g/mol.
4-(2,5-Dimethylbenzoyl)phenyl acetate (C17H16O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
