Description
As a certified reference material (CRM), 1,3-Diphenyl-2-buten-1-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.
CATO supplies 1,3-Diphenyl-2-buten-1-one (CAS 495-45-4), a certified reference material (molecular formula C16H14O, MW 222.28 g/mol) for analytical method development and quality control.
Structurally, 1,3-Diphenyl-2-buten-1-one (C16H14O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 222.28 g/mol, it falls into the medium-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
