Anwendung

Chirales Reagens zur Vorsäulenderivatisierung von Aminosäuren oder Aminoalkoholen, die entstehenden Diastereomere können durch HPLC mit herkömmlichen Reversed-Phase-Säulen getrennt werden.

Biochem./physiol. Wirkung

N-Acetyl-D-penicillamine (NAP or NAPA), a thiol compound, is often used as a control molecule in studies involving nitric oxide donor molecules such as S-nitroso-N-acetyl-dl-penicillamine (SNAP) and sodium nitroprusside (SNP). N-acetyl-D-penicillamine (NAPA) is also used as a heavy metal chelator.
