Description

Styrene-D8 is a deuterated analog of styrene, where eight hydrogen atoms are replaced with deuterium, a stable hydrogen isotope. This isotopic labeling is critical for applications requiring high chemical stability and minimal spectral interference, such as in advanced analytical techniques. It is an essential material for researchers and manufacturers in the pharmaceutical, polymer science, and analytical chemistry sectors who require precise internal standards or labeled precursors for mechanistic studies.

Application

• NMR Spectroscopy Internal Standard: Used as a quantitative and chemical shift reference standard in proton and carbon-13 NMR analysis due to its distinct spectral signature.
• Mass Spectrometry (MS): Serves as a stable isotope-labeled internal standard for the accurate quantification of styrene and its metabolites in complex biological or environmental samples via GC-MS or LC-MS.
• Polymer Research & Development: Acts as a deuterated monomer for synthesizing labeled polymers, enabling detailed studies of polymerization kinetics, chain dynamics, and microstructure via techniques like Small-Angle Neutron Scattering (SANS).
• Metabolic Pathway Tracing: Employed in pharmacological and toxicological research to trace the metabolic fate of styrene in vivo, providing insights into absorption, distribution, metabolism, and excretion (ADME).
• Chemical Reaction Mechanism Studies: Utilized as a probe in mechanistic organic chemistry to investigate reaction pathways, isotope effects, and catalytic processes.
• Environmental Analysis: Functions as a recovery standard or surrogate in analytical methods for detecting and quantifying styrene residues in air, water, and soil.

Quality Control

Our Styrene-D8 is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity, meeting the stringent requirements of research and analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic purity (D, %), chemical purity (by GC), and specific tests for residual solvents and moisture. We adhere to rigorous in-house quality standards to guarantee batch-to-batch consistency and reliability for your critical work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flames. For long-term storage under an inert atmosphere (e.g., argon or nitrogen), please contact us.
