Phosporic acid derivatives represented by formula (I): ##STR1## wherein X is a halogen and R is --(CH.sub.2).sub.n CH.sub.3 (n=0 to 3), or salts thereof are stable to non-enzymatic hydrolysis and are capable of specifically reacting with acid phosphatase. Therefore, the activity of acid phosphatase in the sample can be determined extremely accurately by reacting said compound with a sample containing acid phosphatase and quantitatively determining the reaction product by colorimetry.
式(I)所代表的磷酸衍生物:##STR1##其中X是卤素,R是--(CH.sub.2).sub.n CH.sub.3 (n=0至3),或其盐,对非酶水解稳定,并能特异性地与酸性磷酸酶反应。因此,通过将该化合物与含有酸性磷酸酶的样品反应,并通过比色法定量测定反应产物,可以极其准确地确定样品中酸性磷酸酶的活性。
