The occurrence of 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-bromobenzoate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-bromobenzoate (CAS 413594-59-9), molecular formula C15H8BrNO4 and molecular weight 346.13 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-bromobenzoate (C15H8BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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 1,3-Dihydro-1,3-dioxo-2H-isoindol-2-yl 4-bromobenzoate 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.
