Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-aminobenzoyl)-D-glutamic acid.
(4-aminobenzoyl)-D-glutamic acid (CAS 5959-18-2), molecular formula C12H14N2O5 and molecular weight 266.25 g/mol, is a CATO reference standard with documented purity and traceability.
(4-aminobenzoyl)-D-glutamic acid (C12H14N2O5) contains an amino-acid-derived structure, an amide 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), (4-aminobenzoyl)-D-glutamic 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.
