Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 299.19 g/mol gives (2,4-Dinitrophenyl)aspartic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2,4-Dinitrophenyl)aspartic acid (CAS 26289-22-5), a certified reference material (molecular formula C10H9N3O8, MW 299.19 g/mol) for analytical method development and quality control.
(2,4-Dinitrophenyl)aspartic acid (C10H9N3O8) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2,4-Dinitrophenyl)aspartic acid 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.
