Beta-Alanine-13C3-15N is primarily used in research and scientific studies as a stable isotope-labeled compound. It serves as a tracer in metabolic studies, allowing researchers to track and analyze the pathways and mechanisms of beta-alanine metabolism in biological systems. This labeled form is particularly valuable in NMR (Nuclear Magnetic Resonance) spectroscopy and mass spectrometry, where it helps in identifying and quantifying metabolic intermediates and products with high precision. Additionally, it aids in understanding the role of beta-alanine in muscle carnosine synthesis, which is critical for studies related to exercise performance, muscle fatigue, and endurance. Its application extends to pharmaceutical research, where it assists in drug development and the study of pharmacokinetics.
