Deuterated Methyl methacrylate-d5 | CAS 55935-46-1

OVERVIEW

Deuterated Methyl methacrylate-d5 | CAS 55935-46-1 is a highly valuable isotopically labeled monomer widely used in advanced materials science, polymer chemistry, NMR spectroscopy, and mechanistic studies of methacrylate polymerization. As a fully characterized deuterium-substituted analog of methyl methacrylate, MMA-d5 offers exceptional utility in kinetic investigations, polymer tracking, reaction monitoring, diffusion analysis, and structural elucidation studies that require clear analytical differentiation from non-deuterated components.

At ResolveMass Laboratories Inc., we supply research-grade Deuterated Methyl Methacrylate-d5 with high chemical purity, high isotopic enrichment, and rigorous analytical verification, helping researchers achieve consistent results across polymer characterization, synthetic development, and NMR-based investigations.

STRUCTURAL FEATURES

Deuterated Methyl Methacrylate-d5 retains the same structural and reactivity characteristics as the non-deuterated monomer, with the key difference being the replacement of hydrogen atoms with deuterium. These modifications do not significantly alter the polymerization mechanism but offer precise analytical advantages:

• Improved signal separation in NMR (¹H, ²H, ¹³C)

• Enhanced ability to track polymer chain dynamics

• Reduced background interference in mass spectrometry

• Clear isotopic differentiation for mechanistic studies

Because deuterium has distinct magnetic and vibrational properties, MMA-d5 enables high-resolution analytical tracking in complex polymer systems.

APPLICATIONS of Deuterated Methyl methacrylate-d5 | CAS 55935-46-1

Polymerization Mechanism Studies

MMA-d5 is extensively used to study free-radical, controlled radical, and anionic polymerization pathways. The isotopic labeling allows researchers to follow monomer conversion, chain propagation, termination events, and molecular weight growth through NMR or MS-based techniques.

NMR Spectroscopy

In ¹H NMR, the deuterated positions eliminate interfering proton resonances, enabling improved visualization of reaction intermediates, ester groups, or residual monomer. In ²H NMR, researchers can directly track the distribution of deuterium-labeled monomer within a polymer matrix.

Mass Spectrometric Analysis

The mass shift introduced by deuteration enhances peak separation during LC–MS or GC–MS analysis. This allows for accurate identification of polymer fragments, degradation pathways, and copolymer composition.

Diffusion and Mobility Studies

Deuterium labeling supports neutron scattering and spectroscopic studies focused on polymer diffusion, segmental mobility, and molecular transport in bulk or solution states.

Copolymer Composition and Kinetics

In copolymerization research (e.g., MMA-styrene, MMA-butyl acrylate), MMA-d5 provides unambiguous spectral signatures that enable precise determination of reactivity ratios, monomer sequence distribution, and compositional drift over time.

BENEFITS FOR ANALYTICAL & MATERIALS RESEARCH

High Analytical Clarity

Using a deuterated monomer significantly reduces or eliminates spectral overlap, enabling more accurate quantification and structural assignments.

Enhanced Polymer Characterization

When incorporated into polymer chains, MMA-d5 provides a built-in isotopic marker that facilitates detailed analysis of molecular architecture, tacticity, chain-end structures, and degradation behavior.

Superior Traceability in Formulation Studies

From drug-delivery polymers to specialty acrylics, MMA-d5 enables researchers to track the presence, distribution, and stability of methacrylate monomers in multi-component matrices.

Essential for Mechanistic Research

Deuterated monomers play an important role in mechanistic investigations where proton-specific reactions or isotopic effects can influence chain-growth behavior, activation energy, and reaction kinetics.
