Novel phosphoric acid derivtives represented by general formula (I):
wherein X is a halogen and R is -(CH₂)nCH₃ (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.
通式(I)代表的新型

生物:
其中 X 为卤素,R 为-(CH₂)nCH₃ (n = 0 至 3),或其盐类对非酶
水解稳定,并能与酸性
磷酸酶发生特异性反应。因此,通过使上述化合物与含有酸性
磷酸酶的样品发生反应,并通过比色法定量测定反应产物,可以极其准确地测定样品中酸性
磷酸酶的活性。
