- (S)-N-[1-(1-Naphthyl)ethyl]benzylamine hydrochloride

Chiral Building Block
Utilised in organic synthesis for the construction of complex chiral molecules. Its defined (S)-stereochemistry is critical for stereoselective reactions and the development of enantiomerically pure compounds.
Asymmetric Synthesis Reagent
Acts as a key intermediate in asymmetric synthesis pathways, enabling the control of stereochemistry in the formation of new chiral centres. It is instrumental in producing compounds with specific spatial arrangements.
Chiral Resolution
Employed as a resolving agent to separate enantiomers of racemic mixtures. Its ability to form diastereomeric salts facilitates the isolation of individual enantiomers in chiral resolution processes.
