General description
正丁基锂(n-BuLi)是有机锂试剂，在无机合成中广泛用作强碱（超强碱），用于各种化学中间体的制备。也作为试剂，用于锂卤交换反应和锂-金属的金属交换反应。正丁基锂可锂化碳酸类化合物(carbon acids)。
Application
正丁基锂（2.0 M环己烷溶液）可用作：
- 聚合引发剂，通过阴离子聚合苯乙烯合成聚苯乙烯。
- 强碱，用于非对映选择性烷基化反应。
- 作为试剂与苯甲醛类和二(1H-吡咯-1-yl)四氯化锆反应合成2-苯甲酰基吡咯。
Packaging
建议将25 mL Sure/Seal™瓶作为一次性瓶使用。 反复扎刺可能会使产品性能下降。
