Chemical Structure

2-[(1E)-2-Phenylethenyl]-3-(phenylmethoxy)-4H-pyran-4-one CAS 1206102-05-7 chemical structure

Description

2-[(1E)-2-Phenylethenyl]-3-(phenylmethoxy)-4H-pyran-4-one (CAS 1206102-05-7) is a high-purity analytical reference standard with the molecular formula C20H16O3 and a molecular weight of 304.34 g/mol.

2-[(1E)-2-Phenylethenyl]-3-(phenylmethoxy)-4H-pyran-4-one (C20H16O3) 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.

As a certified reference material (CRM), 2-[(1E)-2-Phenylethenyl]-3-(phenylmethoxy)-4H-pyran-4-one 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.
