Chemical Structure
Description
The molecular framework of 5-Hydroxy-4-phenylisoquinolin-1(2H)-one (C15H11NO2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Hydroxy-4-phenylisoquinolin-1(2H)-one (CAS 656234-16-1) is a high-purity analytical reference standard with the molecular formula C15H11NO2 and a molecular weight of 237.25 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-Hydroxy-4-phenylisoquinolin-1(2H)-one 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.
