General description

Trimethoxy[3-(methylamino)propyl]silane (MAPTMS) is an aminoalkyltrimethoxysilane that can be used for silanization surface immobilization.

Application

MAPTMS can functionalize SBA-15 which can potentially be used for the absorption of carbon dioxide(CO2) and also in novel sensors. It can also be used in the preparation of proton conductive membranes.
Trimethoxy[3-(methylamino)propyl]silane was coated onto a substrate for the preparation of gold dimers by aggregating gold nanospheres. The silane may be used as a silane coupling agent to prepare silica nanoparticles. 2 It may be used to modify quartz substrates.

An alternative method for efficient synthesis of urea-functionalized silanes was proposed on the basis of an N, N'-carbonyldiimidazole-mediated acyl-transfer reaction between various amino-containing building blocks. The employment of different parent aminosilanes and alkylamines afforded an array of urea-containing silanes, which
