General description

N-Ethyl-d5-maleimide is a deuterated isotope analog of N-ethymaleimide, wherein methylene and methyl protons are replaced by deuterium.

Application

N-Ethyl-d5-maleimide can be used:
  • To synthesize isotopic silica nanotag by reacting with silica precursor 3-mercaptopropyltrimethoxysilane (MPTMS) for multiplexed ion beam imaging.
  • As an isotopic internal standard to determine the ratio of glutathione (GSH) and glutathione disulfide (GSSG) in cultured cells using HPLC-UV and LC-QTOF-MS.

Packaging

This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.
