Abstract
There is provided a method for determination of hydroxyacetophenone derivatives such as 3,5-dichloro-4-hydroxyacetophenone in the presence of protein such as albumins or globulins with high sensitivity. The hydroxyacetophenone derivative can be measured in the neutral to acidic region, whereby the method is not affected by interferrants such as bilirubin or hemoglobin. The hydroxyacetophenone derivatives are useful as the chromogen of synthetic substrates for determining acid phosphatase activity.
