CAS 78405-35-3

Urea-13C-15N (9CI)

Description:

Urea-13C-15N (9CI), with the CAS number 78405-35-3, is a stable isotopically labeled compound of urea, where the carbon and nitrogen atoms are replaced with their heavier isotopes, carbon-13 (13C) and nitrogen-15 (15N). This modification allows for enhanced tracking and analysis in various biochemical and environmental studies. Urea itself is a colorless, crystalline substance that is highly soluble in water and is commonly used in fertilizers, as well as in the synthesis of various chemical compounds. The isotopic labeling in Urea-13C-15N makes it particularly useful in research applications such as metabolic studies, tracer experiments, and in the investigation of nitrogen cycles in ecosystems. The presence of these isotopes can be detected using techniques like nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry, providing valuable insights into metabolic pathways and nitrogen utilization in organisms. Overall, Urea-13C-15N serves as a vital tool in both agricultural and environmental research.
