Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(S)-S-Isopropyl 2-((tert-butoxycarbonyl)amino)propanethioate (CAS 1850380-77-6), molecular formula C11H21NO3S and molecular weight 247.35 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-S-Isopropyl 2-((tert-butoxycarbonyl)amino)propanethioate (C11H21NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (S)-S-Isopropyl 2-((tert-butoxycarbonyl)amino)propanethioate 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.
