Chemical Structure
Description
L-Glutamic Acid Di-tert-butyl Ester (CAS 16874-06-9), molecular formula C13H25NO4 and molecular weight 259.34 g/mol, is a CATO reference standard with documented purity and traceability.
L-Glutamic Acid Di-tert-butyl Ester (C13H25NO4) contains an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), L-Glutamic Acid Di-tert-butyl Ester 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.
