Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.26 g/mol gives 3-(1H-Indol-3-yl)isobenzofuran-1(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(1H-Indol-3-yl)isobenzofuran-1(3H)-one (CAS 6936-87-4), molecular formula C16H11NO2 and molecular weight 249.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(1H-Indol-3-yl)isobenzofuran-1(3H)-one (C16H11NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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 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).
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 3-(1H-Indol-3-yl)isobenzofuran-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.
