Application

1-Methyl-2-pyrrolidinone (NMP) has been used as a solvent to study the dispersion ability of acrylate polymers for graphene. It has also been used for the fabrication of working electrodes for electrochemical measurements in a study.

General description

1-Methyl-2-pyrrolidinone, a tertiary amide, is widely employed as an organic solvent. It participates in the sonochemical synthesis of high quality MOF(Metal-Organic Framework)-177 crystals.
It also participates in the following:
  • synthesis of cyanotrimethylsilane
  • decarbonylation of aldehydes
  • reduction of benzaldehydes and ketones to the corresponding alcohols
  • preparation of natural products

Histone-lysine acetylation is a vital chromatin post-translational modification involved in the epigenetic regulation of gene transcription. Bromodomains bind acetylated lysines, acting as readers of the histone-acetylation code. Competitive inhibitors of this interaction have antiproliferative and anti-inflammatory properties.
