應用
苯二醛已用于：
- 采用终点荧光敏感检测的分光光度法检测精氨酸
- 试剂流与样品一起产生荧光产物，以测定海水中的氨含量
- 邻苯二醛分光光度测定（OPA测试），以测定菌株和商用培养物的蛋白水解活性（PA）
生化／生理作用
邻苯二醛（OPA）可在与氨基酸反应时形成荧光衍生物。
苯二醛可用于高效液相色谱（HPLC）分离的氨基酸柱前衍生化。还可用于蛋白质巯基的流式细胞术测定。

Sphingolipid ceramide N-deacylase (SCDase) catalyzes reversible reactions in which the amide linkage in glycosphingolipids is hydrolyzed or synthesized. While SCDases show great value for the enzymatic synthesis of glycosphingolipids, they are relatively poorly characterized enzymes. In this work, the enzymatic
