Chemical Structure
Description
The occurrence of DL-Alanine-2,3,3,3-d4 is closely related to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
DL-Alanine-2,3,3,3-d4 (CAS 53795-92-9), molecular formula C3H3D4NO2 and molecular weight 93.12 g/mol, is a CATO reference standard with documented purity and traceability.
DL-Alanine-2,3,3,3-d4 (C3H3D4NO2) contains deuterium isotope labeling, an amino-acid-derived structure, an amide 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.
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), DL-Alanine-2,3,3,3-d4 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.
