Description
CATO manufactures DL-Methionine-2-d1 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.
CATO supplies DL-Methionine-2-d1 (CAS 67866-74-4), a certified reference material (molecular formula C5H10DNO2S, MW 150.22 g/mol) for analytical method development and quality control.
DL-Methionine-2-d1 (C5H10DNO2S) contains deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid 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.
