Deuterated Styrene-d8 | CAS 19361-62-7

OVERVIEW

Deuterated Styrene-d8 | CAS 19361-62-7  is the fully deuterium-labeled analogue of conventional styrene, in which all eight hydrogen atoms in the molecule are replaced with deuterium (heavy hydrogen, D). This isotopically enriched monomer (chemical formula C₈D₈) retains the core structure of styrene — a vinyl group attached to a phenyl ring — while providing unique analytical and research advantages due to the presence of deuterium. Supplied as a colorless liquid with high isotopic purity (≥98 atom % D), it is typically stabilized with polymerization inhibitors to prevent premature polymerization during storage and handling.

Deuterated Styrene‑d8 is widely utilized in analytical chemistry, polymer research, and materials science, offering enhanced mass differentiation, neutron scattering contrast, and valuable insight into reaction mechanisms.

KEY CHEMICAL PROPERTIES

• CAS Number: 19361‑62‑7

• Molecular Formula: C₈D₈

• Molecular Weight: 112.2 g/mol

The substitution of deuterium for hydrogen increases the molecular weight and slightly alters physical properties while maintaining the functional behavior of the vinyl monomer. The presence of deuterium enables precise quantification and tracking in chemical and polymer studies.

DETAILED DESCRIPTION & ADVANTAGES

Analytical Applications

Deuterated Styrene‑d8 is a preferred internal standard in gas chromatography–mass spectrometry (GC‑MS) and other mass spectrometric analyses. The eight deuterium atoms create a distinct mass shift compared to non-labeled styrene, allowing accurate quantification of styrene in complex mixtures such as environmental samples, consumer products, air, foodstuffs, and biological fluids. Its use ensures high analytical confidence, improved precision, and reliable detection even at trace levels.

NMR and Mechanistic Studies

In nuclear magnetic resonance (NMR) spectroscopy, deuterium does not produce a proton signal, which reduces background interference and simplifies spectral interpretation. Styrene‑d8 is employed in specialized NMR experiments and mechanistic studies where deuterium incorporation can elucidate reaction pathways, kinetic isotope effects, or molecular dynamics. Researchers leverage this compound to study chemical reactions, polymerization kinetics, and molecular mechanisms with enhanced clarity.

Polymer Research and Materials Science

Deuterated Styrene‑d8 can be polymerized to form deuterated polystyrene and related copolymers, which are valuable in high-end materials research. Deuterium’s neutron scattering properties enhance the study of polymer structures, morphology, and phase behavior. These deuterated polymers are crucial for understanding polymer chain dynamics, blend compatibility, and structural properties that are difficult to investigate using standard materials.
