(S)-2-((tert-Butoxycarbonyl)amino)-4-(2,3-dichlorophenyl)butanoic acid (CAS 1260586-97-7), molecular formula C15H19Cl2NO4 and molecular weight 348.22 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-2-((tert-Butoxycarbonyl)amino)-4-(2,3-dichlorophenyl)butanoic acid (C15H19Cl2NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
