1-Phenylpiperazine (1-PP or PP) is a simple chemical compound and drug featuring a phenyl group bound to a piperazine ring. [1] The suffix ‘-piprazole’ is sometimes used in the names of drugs to indicate they belong to this class.
Piperazine is freely soluble in water and ethylene glycol, but insoluble in diethyl ether. It is a weak base with two pK b of 5.35 and 9.73 at 25 °C.; the pH of a 10% aqueous solution of piperazine is 10.8–11.8. Piperazine readily absorbs water and carbon dioxide from the air.
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon groups. [1]
Thieme Synthesis: [1] Patents: [3] [4] [5]. Method E: The reaction between 2-[4-[3-(trifluoromethyl)phenyl]-1-piperazinyl]ethanol [40004-29-3] (1) and Isatoic ...
2,3-Dichlorophenylpiperazine (2,3-DCPP or DCPP) is a chemical compound from the phenylpiperazine family. It is both a precursor in the synthesis of aripiprazole and one of its metabolites .
N-Methylpiperazine is a common building block used in organic synthesis. [2] For example, N-methylpiperazine is used in the manufacture of various pharmaceutical drugs including cyclizine, [3] meclizine, and sildenafil. The lithium salt, lithium N-methylpiperazide, is used as a reagent in organic synthesis for protection of aryl aldehydes. [4]
Perhaps there are better ways to spend our time than cheering for our college sports teams ‘til we’re blue in the face, but we haven’t found them yet.
Phenylhydrazine is used to prepare indoles by the Fischer indole synthesis, which are intermediates in the synthesis of various dyes and pharmaceuticals.. Phenylhydrazine is used to form phenylhydrazones of natural mixtures of simple sugars in order to render the differing sugars easily separable from each other.
