Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxy-7-(p-tolyl)isobenzofuran-1,3-dione.
4-Hydroxy-7-(p-tolyl)isobenzofuran-1,3-dione (CAS 84207-12-5), molecular formula C15H10O4 and molecular weight 254.24 g/mol, is a CATO reference standard with documented purity and traceability.
4-Hydroxy-7-(p-tolyl)isobenzofuran-1,3-dione (C15H10O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 4-Hydroxy-7-(p-tolyl)isobenzofuran-1,3-dione 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.
