CATO supplies (5-Bromo-1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-acetic acid (CAS 5238-66-4), a certified reference material (molecular formula C10H6BrNO4, MW 284.06 g/mol) for analytical method development and quality control.
(5-Bromo-1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-acetic acid (C10H6BrNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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 (5-Bromo-1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-acetic acid 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.
