Chemical Structure
Description
The molecular framework of 2-(7-Chloro-1,3-benzoxazol-2-yl)ethanaminehydrochloride (C9H9ClN2OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-(7-Chloro-1,3-benzoxazol-2-yl)ethanaminehydrochloride (CAS 1158477-55-4), molecular formula C9H9ClN2OHCl and molecular weight 233.09 g/mol, is a CATO reference standard with documented purity and traceability.
