Chemical Structure
Description
3-([1,1'-Biphenyl]-4-yloxy)butan-2-one (CAS 28089-74-9) is a high-purity analytical reference standard with the molecular formula C16H16O2 and a molecular weight of 240.30 g/mol.
3-([1,1'-Biphenyl]-4-yloxy)butan-2-one (C16H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-([1,1'-Biphenyl]-4-yloxy)butan-2-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.
