(r)-2-Amino-2-(3-chloro-4-fluorophenyl)ethan-1-ol (CAS 933786-63-1), molecular formula C8H9ClFNO and molecular weight 189.61 g/mol, is a CATO reference standard with documented purity and traceability.
(r)-2-Amino-2-(3-chloro-4-fluorophenyl)ethan-1-ol (C8H9ClFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
