Chemical Structure
Description
L-Methionine-3,3,4,4 D4 (CAS 67866-75-5), molecular formula C5H7D4NO2S and molecular weight 153.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of L-Methionine-3,3,4,4 D4 (C5H7D4NO2S) is characterized by deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 L-Methionine-3,3,4,4 D4 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.
