Deuterated 3-(Trimethoxysilyl)propyl methacrylate-d5 | CAS 2530-85-0

OVERVIEW

Deuterated 3-(Trimethoxysilyl)propyl methacrylate-d5 | CAS 2530-85-0 is a specialized isotopically labeled silane coupling agent engineered to support advanced analytical, materials science, and surface-modification applications. As the deuterated analogue of the widely used TMSPMA, this compound integrates the reactive methacrylate functionality with a trimethoxysilane group while incorporating deuterium (D5) substitution for enhanced spectroscopic detectability.

Because of its dual reactivity—methacrylate polymerization and silane surface attachment—this molecule enables precise control over molecular tracking, interface engineering, and reaction pathway elucidation. The presence of deuterium significantly improves signal clarity in NMR, MS, and vibrational spectroscopy, making the compound an essential tool for research in polymer chemistry, nanomaterials, and surface engineering.

KEY FEATURES

• Isotopically labeled with five deuterium atoms (D5) for superior analytical resolution

• Dual functionality: methacrylate for polymerization + silane for surface attachment

• Highly reactive toward hydroxyl-rich substrates such as glass, silica, and metal oxide surfaces

• Excellent for mechanistic studies, polymer tracing, and spectroscopic investigations

• Supports the design of hybrid organic–inorganic materials

MECHANISM OF ACTION

The compound features two reactive domains:

1. Silane Reactivity

The trimethoxysilane group undergoes hydrolysis to form silanols, followed by condensation with surface hydroxyl groups. This results in robust, covalent Si–O–Si linkages on:

• Silica nanoparticles

• Glass substrates

• Oxide surfaces (TiO₂, Al₂O₃, ITO)

2. Methacrylate Reactivity

The methacrylate moiety participates in free-radical polymerization. Once bonded to a substrate, the molecule can initiate or propagate organic polymer coatings and crosslinked networks.

The combination of these mechanisms supports the creation of strong, durable organic–inorganic interfaces.
