개요
다이아졸2(두 개의 질소 원자와 세 개의 탄소 원자로 이루어진 다섯 원자 고리 화합물).화학적 성질
white to yellow crystals or crystalline powder용도
Pyrazole is used in organic synthesis and asa chelating agent.정의
ChEBI: 1H-pyrazole is the 1H-tautomer of pyrazole. It is a conjugate base of a pyrazolium. It is a conjugate acid of a pyrazol-1-ide. It is a tautomer of a 3H-pyrazole and a 4H-pyrazole.일반 설명
Pyrazine is a heterocyclic crystalline aromatic compound with a five-membered ring containing three carbon atoms and two nitrogen atoms. It is a symmetricdiazine.위험도
Toxic by ingestion and inhalation, irritant to skin and eyes.건강위험
The acute toxic symptoms from oral administrationof pyrazole in experimental animalswere ataxia, muscle weakness, and respiratorydepression. It is less toxic than pyrroleand pyrrolidine. The oral LD50 value in miceis within the range 1450 mg/kg.Pyrazole exhibited reproductive toxicityin rats and mice when administered by oralor intraperitoneal route. The effects includefetal death, developmental abnormalities pertainingto the urogenital system, and postimplantationmortality.
화재위험
Noncombustible solid.Safety Profile
Moderately toxic by ingestion and intraperitoneal routes. Experimental teratogenic and reproductive effects. When heated to decomposition it emits toxic fumes of NOx.Purification Methods
Crystallise pyrazole from pet ether, cyclohexane, or water. Its solubility in H2O at 9.6o is 2.7moles/L, and at 24.8o it is 19.4moles/L; in cyclohexane at 31.8o it is 0.577moles/L, and at 56.2o it is 5.86moles/L; and in benzene at 5.2o it is 0.31moles/L, and at 46.5o it is 16.8moles/1000mL.
