Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dibenzyl aspartate 4-methylbenzenesulfonate.
CATO supplies Dibenzyl aspartate 4-methylbenzenesulfonate (CAS 4079-62-3), a certified reference material (molecular formula C18H19NO4C7H8O3S, MW 485.55 g/mol) for analytical method development and quality control.
Dibenzyl aspartate 4-methylbenzenesulfonate (C18H19NO4C7H8O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Dibenzyl aspartate 4-methylbenzenesulfonate 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.
