General description
亚硫酸氢钠的水溶液性质是酸性的。用酸降解亚硫酸氢钠形成二氧化硫气体。
由于亚硫酸氢钠的抗氧化和抗菌作用，它是一种应用广泛的工业化学品，它可被用作还原剂、催化剂和防腐剂。
Application
亚硫酸氢钠（NaHSO3）已用作组成免疫沉淀（IP）缓冲液的试剂，用于化学修饰 DNA 和合成砷脂（AsL）。
它还可用作合成 5，6-二氢尿嘧啶-6 的试剂磺酸盐。
它还可用作合成 5，6-二氢尿嘧啶-6 的试剂磺酸盐。
亚硫酸氢钠可被用作：
- 由芳香族和脂肪族醛合成醛-亚硫酸氢盐加合物的试剂。
- 芳香族/脂肪醇无溶剂醚化通过分子间脱水合成对称和不对称醚的催化剂。
- 铜催化酮肟羧酸盐自偶联合成对称吡咯的添加剂。
