Chemical Structure
Description
The occurrence of D-Glutamic acid, 4-hydroxy-, erythro- is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
D-Glutamic acid, 4-hydroxy-, erythro- (CAS 6148-21-6) is a high-purity analytical reference standard with the molecular formula C5H9NO5 and a molecular weight of 163.13 g/mol.
The molecular framework of D-Glutamic acid, 4-hydroxy-, erythro- (C5H9NO5) is characterized by a carbohydrate-derived structure, an amide group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures D-Glutamic acid, 4-hydroxy-, erythro- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
