N-[(tert-Butoxy)carbonyl]-L-tryptophan Usage And Synthesis

Chemical Properties	WHITE TO OFF-WHITE GRANULAR POWDER
Uses	Nα-Boc-L-tryptophan is an N-Boc-protected form of L-Tryptophan (T947210). L-Tryptophan is an essential amino acid that is important for cell proliferation and the biosynthesis of proteins. It is a precursor to Serotonin (HCl: S274980), a neurotransmitter that compound that aids in sleep and mental state. L-Tryptophan is also thought to cause eosinophilia-myalgia syndrome.
