Description

Styrene-Alpha,β-13C2 is a stable isotope-labeled analog of styrene, specifically labeled with carbon-13 at the alpha and beta positions of the vinyl group. This compound is essential as an internal standard and tracer in advanced analytical chemistry, enabling precise quantification and metabolic pathway elucidation. It is primarily required by research institutions, pharmaceutical developers, and analytical laboratories engaged in mass spectrometry, NMR spectroscopy, and environmental fate studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of styrene and its metabolites in complex biological and environmental matrices via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Serves as a critical tracer in pharmacokinetic and toxicological studies to investigate the absorption, distribution, metabolism, and excretion (ADME) of styrene.
• NMR Spectroscopy Studies: Provides distinct signals in 13C NMR for structural analysis and reaction mechanism studies involving styrene polymerization or copolymerization.
• Environmental Analysis: Employed in tracer studies to monitor the degradation, bioaccumulation, and environmental fate of styrene monomers.
• Polymer Science Research: Used to study polymerization kinetics, mechanism, and the microstructure of resulting polymers and copolymers.
• Quality Control & Method Development: Acts as a reference material for validating and calibrating analytical methods in regulatory and quality control laboratories.
