1,1-Diphenylbut-1-ene (CAS 1726-14-3), molecular formula C16H16 and molecular weight 208.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 1,1-Diphenylbut-1-ene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Diphenylbut-1-ene 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.
