1-Naphthaleneacetic acid is stable under normal temperatures and pressures but is prone to decomposition in damp environments. It should be stored in a cool, dry, and well-ventilated place, away from foodstuffs and protected from light.
1-Naphthaleneacetic acid is primarily used as a plant growth regulator. It is absorbed by the roots, stems, and leaves of plants and has the ability to stimulate plant growth. It is widely used in agriculture, forestry, vegetables, flowers, fruit trees, and other fields to induce the formation of adventitious roots, improve the survival rate of tree cuttings, increase fruit set rates, and prevent pre-harvest fruit drop.
