Chemical Structure
Description
1,3-Diphenylisobenzofuran-5,6-dicarbaldehyde (CAS 64218-56-0) is a high-purity analytical reference standard with the molecular formula C22H14O3 and a molecular weight of 326.34 g/mol.
The molecular framework of 1,3-Diphenylisobenzofuran-5,6-dicarbaldehyde (C22H14O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1,3-Diphenylisobenzofuran-5,6-dicarbaldehyde 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.
