Chemical Structure
Description
L-Methionine-S-methyl Sulfonium Chloride-d (CAS 362049-54-5) is a high-purity analytical reference standard with the molecular formula C6H8D6NO2SCl and a molecular weight of 205.73 g/mol.
The molecular framework of L-Methionine-S-methyl Sulfonium Chloride-d (C6H8D6NO2SCl) is characterized by deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), L-Methionine-S-methyl Sulfonium Chloride-d 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.
