Product Description
2-(3-Chlorophenoxy)acetic Acid (3-CPA) is a synthetic Plant Growth Regulator belonging to the phenoxyacetic acid family. It functions as an auxin-like compound widely used in agricultural systems to regulate plant growth, improve fruit set, and control physiological development processes in horticultural and field crops.
In modern precision agriculture, 3-CPA is frequently integrated into formulations with Foliar Fertilizers, Growth Promoters, and Plant Extracts to enhance crop productivity and uniformity. It is also used as a reference compound in agrochemical research and formulation development for auxin-based regulatory systems.
Content Note: Prepared by our technical team based on current scientific literature. Agricultural claims comply with international regulatory guidelines. Last reviewed: April 2026
According to a study in Scientia Horticulturae (2003), phenoxyacetic acid derivatives such as 3-CPA may influence fruit set regulation and early developmental signaling in horticultural crops.
A study published in Plant Growth Regulation (2008) suggests that auxin analogues can modulate cell elongation and reproductive organ retention in fruit-bearing plants.
