CATO supplies 4-[(1E)-3-(4-Methylphenyl)-3-oxoprop-1-en-1-yl]phenyl (2E)-3-phenylprop-2-enoate (CAS 331460-44-7), a certified reference material (molecular formula C25H20O3, MW 368.42 g/mol) for analytical method development and quality control.
Structurally, 4-[(1E)-3-(4-Methylphenyl)-3-oxoprop-1-en-1-yl]phenyl (2E)-3-phenylprop-2-enoate (C25H20O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 368.42 g/mol, it falls into the moderately-high-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), 4-[(1E)-3-(4-Methylphenyl)-3-oxoprop-1-en-1-yl]phenyl (2E)-3-phenylprop-2-enoate 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.
