white to light beige powder
Uses
4-chlorophenoxy acetic acid (4-CPA), a chlorine derivative of phenoxyacetic acid (PA), is a plant growth regulator used as a herbicide.
Uses
2-(4-Chlorophenoxy)acetic Acid is used in the synthesis of a new class of hypoxia-inducible factor-1 inhibitors.
Definition
ChEBI: A chlorophenoxyacetic acid that is phenoxyacetic acid carrying a chloro substituent at position 4.
General Description
4-Chlorophenoxyacetic acid is a herbicide. Degradation of 4-chlorophenoxyacetic acid in aqueous medium by advanced electrochemical oxidation processes, using an undivided cell containing a Pt anode has been reported.
Hazard
Moderately toxic; mutagen.
Biochem/physiol Actions
4-Chlorophenoxyacetic acid is a synthetic auxin, that is used to induce parthenocarpic ovary growth on flowers of wild type plants.
Safety Profile
Moderately toxic by
ingestion and intraperitoneal routes. Human
mutation data reported. When heated to
decomposition it emits toxic fumes of Cl-.
Purification Methods
Crystallise the acid from EtOH. It is a plant growth substance and a herbicide. [Beilstein 6 IV 845.]
