2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH 2) 4 NH. It is a cyclic secondary amine , also classified as a saturated heterocycle . It is a colourless liquid that is miscible with water and most organic solvents.
N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
Subsequently, Formyl peptide receptor 2 and Formyl peptide receptor 3 were also cloned based on the similarities in their amino acid sequence to that of formyl peptide receptor 1. Formyl peptide receptors 2 and 3 have very different abilities to bind and respond to formylated oligopeptides including fMLF compared to formyl peptide receptor 1 ...
N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
Solution of PVDF 1−2% by mass in N-methyl-2-pyrrolidone (NMP) is mixed with an active lithium storage material such as graphite, silicon, tin, LiCoO 2, LiMn 2 O 4, or LiFePO 4 and a conductive additive such as carbon black or carbon nanofibers.
This electrophile attacks the C-2 carbon of an unoxidized molecule of pyrrole to give a dimeric cation [(C 4 H 4 NH) 2] ++. The process repeats itself many times. Conductive forms of PPy are prepared by oxidation ("p-doping") of the polymer: (C 4 H 2 NH) n + 0.2 X → [(C 4 H 2 NH) n X 0.2] The polymerization and p-doping can also be effected ...
It has a low vapor pressure, and is nearly odorless. [2] It has a low solubility in water, but is soluble in a variety of organic solvents. CHP is used in the electronics industry as a photoresist stripper (usually in combination with other solvents like N-methyl-2-pyrrolidone), and as a chemical polisher of copper in circuit board fabrication.
