Description

Dl-Alanine (3-13C) CAS NO 131157-42-1 is a stable isotope-labeled analog of the amino acid alanine, where the carbon atom at the 3-position is enriched with the carbon-13 isotope. This compound is essential for advanced research and development in fields requiring precise metabolic and biochemical pathway tracing. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors for applications such as NMR spectroscopy, mass spectrometry, and metabolic studies.

Application

• Metabolic Pathway Tracing: Used as a tracer in NMR (Nuclear Magnetic Resonance) and MS (Mass Spectrometry) studies to elucidate biochemical pathways and flux analysis.
• Pharmaceutical Research: Serves as a critical reagent in the development and testing of new drugs, particularly in pharmacokinetic and metabolic stability studies.
• Biochemical Assay Development: Employed as an internal standard for the accurate quantification of alanine and related metabolites in complex biological matrices.
• Nutritional Science Research: Used in studies investigating protein metabolism, amino acid turnover, and nutritional labeling in vivo.
• Isotope Dilution Mass Spectrometry (IDMS): Acts as a high-purity standard for the precise and accurate measurement of alanine concentrations in clinical and research samples.
• Manufacturing of Labeled Compounds: Serves as a building block for the synthesis of more complex carbon-13 labeled peptides, proteins, or other biochemicals.
