Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Methyl-[1,1'-biphenyl]-3-yl)ethan-1-one.
1-(2-Methyl-[1,1'-biphenyl]-3-yl)ethan-1-one (CAS 1256479-48-7), molecular formula C15H14O and molecular weight 210.27 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Methyl-[1,1'-biphenyl]-3-yl)ethan-1-one (C15H14O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
