Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 1-([1,1'-Biphenyl]-2-yl)-2-phenylethanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.34 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.
1-([1,1'-Biphenyl]-2-yl)-2-phenylethanone (CAS 229970-97-2), molecular formula C20H16O and molecular weight 272.34 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), 1-([1,1'-Biphenyl]-2-yl)-2-phenylethanone 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.
