Compared with other compounds in its class, the molecular weight of 526.62 g/mol gives 3-Benzylidene-4,5,6,7-tetraphenylisobenzofuran-1(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Benzylidene-4,5,6,7-tetraphenylisobenzofuran-1(3H)-one (CAS 52986-57-9), a certified reference material (molecular formula C39H26O2, MW 526.62 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 3-Benzylidene-4,5,6,7-tetraphenylisobenzofuran-1(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 526.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
