Chemical Structure
Description
The occurrence of L-Glutamic-2,4,4-d3 Acid is closely related to deuterium isotope labeling, a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies L-Glutamic-2,4,4-d3 Acid (CAS 203805-84-9), a certified reference material (molecular formula C5H6D3NO4, MW 150.15 g/mol) for analytical method development and quality control.
The molecular framework of L-Glutamic-2,4,4-d3 Acid (C5H6D3NO4) is characterized by deuterium isotope labeling, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures L-Glutamic-2,4,4-d3 Acid 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.
