| Biological Activity | Chlorophenol red is a pH indicator. It is used as an optical transducer of acetyl cholinesterase inhibition by the analytes. Chlorophenol red is also used to selectively determine chlorine dioxide in drinking water. It has been used in the novel assay to detect transformed protoplast-derived Zea mays colonies on Phosphinothricin (PPT). |
| Purification Methods | Crystallise the dye from glacial acetic acid. It is yellow at pH 4.8 and violet at pH 6.7. [Beilstein 19/3 V 458.] |
