产品应用

⑴.无色至黄色透明液体，溶液暴露于空气或湿气时易起火。
⑵.用于制备各种烷基、芳基衍生物的有机金属化合物，是生产太阳能电池的原料。
⑶.是重要的锂试剂。与卤代烷和有机化合物中的活性氢交换而将铿原子引入其中，继而可进行许多反应。也用作聚合反应引发剂。
⑷.作为强碱，用于锂-卤交换反应或锂-金属转移金属化反应。
①.作为异丁基锂和叔丁基锂的同类物质，正丁基锂的碱性和反应活性都较差一些，但对于含活泼氢的底物，却是一个有效的脱质子试剂，特别是当形成的是杂原子阴离子或形成的碳阴离子能够被共轭效应稳定（如阴离子在sp
本品（n-C4H9Li）为主要用于有机反应催化剂广泛用于药物中间体，液晶单体，农药及橡胶业的有机催化反应。
