Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-butyl (2S)-2-(2-chloroacetamido)-3-methylbutanoate (CAS 1909295-01-7), molecular formula C11H20ClNO3 and molecular weight 249.73 g/mol, is a CATO reference standard with documented purity and traceability.
tert-butyl (2S)-2-(2-chloroacetamido)-3-methylbutanoate (C11H20ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures tert-butyl (2S)-2-(2-chloroacetamido)-3-methylbutanoate 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.
