Chemical Structure
Description
The occurrence of 3-Phenylphthalide is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Phenylphthalide (CAS 5398-11-8), a certified reference material (molecular formula C14H10O2, MW 210.23 g/mol) for analytical method development and quality control.
3-Phenylphthalide (C14H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Phenylphthalide 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.
