Description

Butanedioic Acid-1,4-13C2 is a stable isotope-labeled analog of succinic acid, where two carbon atoms at the 1 and 4 positions are replaced with the 13C isotope. This product is essential for advanced research and analytical applications requiring precise metabolic pathway tracing and quantification. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and agrochemical industries for use as an internal standard in mass spectrometry, NMR spectroscopy, and metabolic flux analysis.

Application

• Internal standard for the accurate quantification of succinic acid and related metabolites in complex biological matrices via LC-MS/MS and GC-MS.
• Tracer compound for studying the tricarboxylic acid (TCA) cycle and other central carbon metabolic pathways in cell culture and in vivo models.
• Critical reagent in the development and validation of clinical diagnostic assays for metabolic disorders.
• Use in isotope dilution mass spectrometry (IDMS) methods to ensure high accuracy and precision in analytical measurements.
• Precursor for the synthesis of more complex 13C-labeled fine chemicals, pharmaceuticals, and agrochemicals.
• Research tool in metabolomics and systems biology to elucidate biochemical mechanisms and discover biomarkers.
