As a newtype cleaning agent, 1-bromopropane not only has the same outstanding cleaning effect to CFC-113, but has better cleaning efficiency than it, especially cleaning metal parts. 1-bromopropane has no flash point, it can be repetitive-used, and its craft was complete unification with CFC-113 and TCA. Using 1-bromopropane as a cleaning agent, it is not necessary to replace the cleaning equipment but only adjusting the temperature of distillation and abstersion.

1-溴丙烷(英文名1-bromopropane，简称n-PBr)作为新型的清洗剂，其清洗效果可与CFC-113媲美，且清洗效率比CFC-113高，对于金属零件的清洗能力更强，没有闪点，可以重复回收使用，替代CFC-113和TCA，工艺完全一致，几乎不需要更换设备，只需要调整一下蒸洗温度就可以了，也被称为是"第三世界的替代清洗剂"。
