| | 4-Fluorophenoxyacetic acid Usage And Synthesis |
| Chemical Properties | white to light beige crystalline powder | | Uses | 4-Fluorophenoxyacetic acid (4FPA) induces parthenocarpy. 4-Fluorophenoxyacetic acid (4FPA) protects cereals from piercing-sucking insects and thereby increases rice yield in the field[1][2]. | | Purification Methods | Crystallise the acid from EtOH or H2O.
