Description

trans-Stilbene-α,β-13C2 is a stable isotope-labeled analog of trans-stilbene, specifically enriched with carbon-13 at the alpha and beta positions of the ethylene bridge. This compound is essential for advanced analytical research, providing an internal standard for precise quantification and mechanistic studies using techniques like NMR and mass spectrometry. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries who require high-fidelity isotopic tracers.

Application

• As an internal standard for the accurate quantification of stilbene derivatives or related compounds in complex matrices using LC-MS or GC-MS.
• In NMR spectroscopy studies to investigate reaction mechanisms, metabolic pathways, or molecular dynamics due to its distinct 13C signature.
• For pharmaceutical research, particularly in the development and validation of analytical methods for drug substances and metabolites.
• In material science research for studying photophysical properties, energy transfer, or as a building block in the synthesis of labeled organic electronic materials.
• As a tracer in environmental fate studies or agrochemical research to monitor the degradation and translocation of compounds.
• For synthesis of more complex 13C-labeled compounds where the labeled ethylene unit needs to be incorporated.
