Application

Polyglycine serves as a valuable tool in various advanced spectroscopic and analytical techniques. It is primarily used as an external intensity standard for cross polarization (CP) nuclear magnetic resonance (NMR) spectrum measurements and ion mobility mass spectrometry, enabling accurate and reliable data analysis. Additionally, its structure, consisting of repeating glycine units linked by amide bonds, makes it an effective model for studies in UV resonance Raman spectroscopy. Its unique properties and composition allow researchers to explore a range of scientific phenomena with enhanced precision.
