Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 11-(Dansylamino)undecanoic acid, 97%.
CATO supplies 11-(Dansylamino)undecanoic acid, 97% (CAS 73025-02-2), a certified reference material (molecular formula C23H34N2O4S, MW 434.59 g/mol) for analytical method development and quality control.
11-(Dansylamino)undecanoic acid, 97% (C23H34N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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), 11-(Dansylamino)undecanoic acid, 97% 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.
