Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl N-(3-chlorophenyl)-N-(methylsulfonyl)-L-alaninate.
Methyl N-(3-chlorophenyl)-N-(methylsulfonyl)-L-alaninate (CAS 1008436-64-3), molecular formula C11H14ClNO4S and molecular weight 291.75 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl N-(3-chlorophenyl)-N-(methylsulfonyl)-L-alaninate (C11H14ClNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
