Description

trans-Styrene-(Beta)-D is a deuterated isotopologue of styrene, where a deuterium atom replaces a specific hydrogen atom on the β-carbon of the vinyl group. This compound is a valuable analytical standard and a crucial building block in advanced organic synthesis, particularly for mechanistic studies and the development of novel materials. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require precise isotopic labeling for applications in NMR spectroscopy, mass spectrometry, and kinetic isotope effect investigations.

Application

• NMR Spectroscopy Internal Standard: Used as a quantitative and structural reference standard in proton and deuterium NMR due to its defined isotopic purity.
• Mechanistic Reaction Studies: Employed in kinetic isotope effect (KIE) experiments to elucidate reaction pathways and transition states in organic and organometallic chemistry.
• Deuterated Polymer Synthesis: Serves as a monomer for creating deuterated polystyrene, which is essential for neutron scattering studies of polymer dynamics and structure.
• Pharmaceutical Research: Acts as a labeled precursor in the synthesis of deuterated drug candidates to study metabolism, bioavailability, and stability.
• Mass Spectrometry Tracer: Functions as a stable isotope-labeled tracer in GC-MS and LC-MS analyses for accurate quantification and metabolic profiling.
• Material Science Research: Used in the development of specialty optical and electronic materials where isotopic purity can influence physical properties.

Quality Control

Our trans-Styrene-(Beta)-D is produced and handled under strict quality protocols to ensure high isotopic and chemical purity suitable for research and synthesis. Each batch is characterized by advanced analytical techniques including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (atom % D), chemical purity, and identity confirmation is provided with every shipment to guarantee traceability and compliance with your research specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). For long-term storage under an inert atmosphere (e.g., argon or nitrogen) is recommended to maintain stability and prevent polymerization.
