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 2-Bromo-4-(1,3-diketoisoindolin-2-yl)butyraldehyde.
CATO supplies 2-Bromo-4-(1,3-diketoisoindolin-2-yl)butyraldehyde (CAS 133118-36-2), a certified reference material (molecular formula C12H10BrNO3, MW 296.12 g/mol) for analytical method development and quality control.
2-Bromo-4-(1,3-diketoisoindolin-2-yl)butyraldehyde (C12H10BrNO3) 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, 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.
As a certified reference material (CRM), 2-Bromo-4-(1,3-diketoisoindolin-2-yl)butyraldehyde 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.
