Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 284.35 g/mol gives 5-Methyl-1,3-diphenylisobenzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Methyl-1,3-diphenylisobenzofuran (CAS 27720-46-3), a certified reference material (molecular formula C21H16O, MW 284.35 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-1,3-diphenylisobenzofuran (C21H16O) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Methyl-1,3-diphenylisobenzofuran 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.
