Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies L-Glutamic acid diallyl ester (tosylate) (CAS 20845-16-3), a certified reference material (molecular formula C11H17NO4C7H8O3S, MW 399.46 g/mol) for analytical method development and quality control.
L-Glutamic acid diallyl ester (tosylate) (C11H17NO4C7H8O3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), L-Glutamic acid diallyl ester (tosylate) 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.
