(R)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-ethylmethanesulfonamide (CAS 1176633-06-9), molecular formula C11H16ClNO3S and molecular weight 277.77 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-N-(4-(2-Chloro-1-hydroxyethyl)phenyl)-N-ethylmethanesulfonamide (C11H16ClNO3S) 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, 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.
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.
