| 4-Bromophenylacetic acid Usage And Synthesis |
| Chemical Properties | White Solid | | Uses | 4-Bromophenylacetic acid was used as standard in the extraction of nonylphenol polyethoxy carboxylates with 1-4 ethoxy groups from sludge samples. | | Biochem/physiol Actions | 4-Bromophenylacetic acid is a growth inhibitory substance. It causes the depolarization effect on the transmembrane potential difference of tobacco protoplasts isolated from two genotypes differing in their sensitivity to auxins. | | Purification Methods | The acid crystallises from H2O as needles. The acid chloride has b 238o/760mm, m 50o, and the anilide has m 174-175o. [Dippy & Williams J Chem Soc 161 1934, 1251 1948, Schwenk & Pala J Org Chem 11 798 1946, Beilstein 9 III 2275.] |
