Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3,3-Diphenylisobenzofuran-1(3H)-one is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1198.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 3,3-Diphenylisobenzofuran-1(3H)-one (CAS 596-29-2), a certified reference material (molecular formula C55H87N13O13C2H4O2, MW 1198.43 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3,3-Diphenylisobenzofuran-1(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
