Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C 4 H 4 N 2. It is a symmetrical molecule with point group D 2h. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. It is a "deliquescent crystal or wax-like solid with a pungent, sweet, corn-like, nutty odour". [3]
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can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
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.
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. [2] It is a rigid analogue of amphetamine.
Aminoethylpiperazine (AEP) is a derivative of piperazine. This ethyleneamine contains three nitrogen atoms; one primary, one secondary and one tertiary. It is a corrosive organic liquid and can cause second or third degree burns. Aminoethylpiperazine can also cause pulmonary edema as a result of inhalation. It is REACH and TSCA registered. [1]
Substituted piperazines are a class of chemical compounds based on a piperazine core. [1] Some are used as recreational drugs and some are used in scientific research . [ 2 ]
