L-ASPARAGINE:H2O (AMIDE-15N+) is a labeled, naturally occurring amino acid derivative in which the amide nitrogen of L-asparagine is enriched with 15N and associated with water, forming an amino acid-water adduct. The molecule contains an amino group and a carboxyl group characteristic of asparagine, with a side-chain primary amide that provides hydrogen-bonding functionality, while the isotopic labeling is localized to the amide nitrogen for traceable nitrogen chemistry. In biochemical and analytical workflows, this labeled compound is used as an isotopic tracer and substrate analogue for nitrogen incorporation studies, mass spectrometric or NMR method development, and the preparation of more complex asparagine-containing amino acid and peptide derivatives where retention of the labeled amide nitrogen is required.
