The Uses of 4-Bromophenylacetic acid
4-Bromophenylacetic acid was used as standard in the extraction of nonylphenol polyethoxy carboxylates with 1-4 ethoxy groups from sludge samples.
Definition
ChEBI: 4-Bromophenyl acetate is a monocarboxylic acid.
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.]
