CAS: 35277-02-2; 4-Fluoro-1H-Pyrazole

该化合物是一种环状环状的杂交有机化合物,由5个成员组成,包括两个相邻的氮原子; 环状4位置的氟原子的存在,对其化学特性和再活动有重大影响; 该化合物一般无色可粉黄黄色液体或固体,因其形态和纯度而不同; 因其在药用化学中的应用,特别是在制药方面的应用,因其与生物目标相互作用的能力而闻名; 化合物在极地溶剂中表现出中等溶性,在标准条件下相对稳定; 其再活动可归因于氟质原子的电阻性质,这可以增强对丙烯环上其他位置的核分裂性攻击; 此外, 4-氟-1H-pyrazoole可参与各种化学反应,包括替代和组合反应,使其成为有机合成中有价值的中间体; 在处理这一化合物时,应当注意安全防范措施,如同许多含氟的有机物质一样.
