OVERVIEW

Deuterated Ethyl-d5 methacrylate | CAS 55935-46-1 is a high-purity, isotopically labeled monomer designed for advanced analytical, polymer research, and mechanistic studies. Structurally analogous to standard ethyl methacrylate but containing five deuterium atoms, this molecule offers enhanced spectral clarity and tracer capabilities across NMR, MS, polymerization tracking, and reaction-pathway investigations. Its stability, compatibility with radical polymerization systems, and clean isotopic signature make it a valuable reagent in academic, pharmaceutical, and materials-science environments.

As a specialty deuterated methacrylate, it is frequently used to synthesize labeled polymers, investigate degradation pathways, quantify copolymer compositions, monitor polymer chain mobility, and perform structural studies with minimal background interference. ResolveMass Laboratories Inc. supports researchers with materials optimized for reproducibility, analytical rigor, and demanding experimental use cases.

Deuteration reduces proton-related spectral noise, improving accuracy in NMR and MS-based studies. This allows researchers to track polymer structure, dynamics, and monomer reactivity with greater precision.

3. Excellent Compatibility with Polymerization Systems
The methacrylate double bond readily participates in free-radical polymerizations, enabling the synthesis of labeled homopolymers, copolymers, and block polymers.

4. Ideal for Mechanistic Research
The isotopic label supports in-depth study of chain-transfer behavior, degradation kinetics, radical propagation, and structural rearrangements.

5. Suitable for Quantitative and Qualitative Analysis
It enhances analytical differentiation in mixed systems, aiding in copolymer ratio measurement, molecular mobility assessment, and degradation product identification.
