4-Chlorophenoxyacetic acid Chemical Properties,Uses,Production
Chemical Properties
white to light beige powder
Uses
2-(4-Chlorophenoxy)acetic Acid is used in the synthesis of a new class of hypoxia-inducible factor-1 inhibitors.
Uses
4-chlorophenoxy acetic acid (4-CPA), a chlorine derivative of phenoxyacetic acid (PA), is a plant growth regulator used as a herbicide.
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.]
