过一硫酸氢钾复合盐（potassium peroxymonosulfate）又称卡卢酸钾（potassium caroate），简称过一硫酸氢钾、过硫酸氢钾，化学式为2KHSO5·KHSO4·K2SO4。
它是过一硫酸氢钾、硫酸氢钾和硫酸钾组成的复盐，商品名为Caroat或Oxone，常用作有机合成中的氧化剂，且广泛用于清洗，其可美白义齿[1]，消毒游泳池[2]，用于微电子制造的清洁芯片[3][4]。
过一硫酸氢根离子与硫酸氢根离子的半反应的标准电极电势值为-1.44V：
- HSO4− + H2O → HSO5− + 2 H+ + 2 e−
氧化硫醚时的中间产物亚砜较不易被转化为砜，因此与硫醚以1:1计量反应得到亚砜，以2:1计量得到砜：[6]
