Application
Hexadecylpyridinium chloride is used as a component of cationic and mixed micelles and in nanoparticle and hydrogel compositions. Used for detergent-based extraction of membrane-associated enzymes such as alkaline phosphatase, and in extraction of chromium and palladium.

状白色固体粉末，常带一分子的结晶水，其熔点为77～83℃。极易溶于水、乙醇，可溶于氯仿，几乎不溶于苯、乙醚。1%的水溶液PH为6.0～7.0。强力振荡其水溶液会产生丰富的泡沫。具有良好的表面活性和杀菌消毒性能。
