Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 69716-53-6 2-(4-phenylphenyl)-1,2-dihydronaphthalene DTXSID20377564.
69716-53-6 2-(4-phenylphenyl)-1,2-dihydronaphthalene DTXSID20377564 (CAS 69716-53-6), molecular formula C22H18 and molecular weight 282.38 g/mol, is a CATO reference standard with documented purity and traceability.
69716-53-6 2-(4-phenylphenyl)-1,2-dihydronaphthalene DTXSID20377564 (C22H18) contains 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
