Basic Information

Abscisic Acid
ABA

Abscisic acid, commonly abbreviated ABA, is a plant hormone supplied as a white to off-white powder. It has limited water solubility but dissolves in several organic solvents and sodium bicarbonate solution. Typical applications include plant physiology research, agricultural growth-regulation formulations and ecological vegetation restoration. Its documented physiological roles involve dormancy, stomatal behavior, embryo development and responses to environmental stress.

Abscisic Acid (ABA) Technical Grade Powder CAS#21293-29-8

This high-purity product is a white to off-white powder with excellent solubility for wide formulation use. It dissolves readily in common organic solvents including acetone, chloroform and ethyl acetate, as well as sodium bicarbonate solution. By contrast, it is only slightly soluble in water, benzene and petroleum ether.


Applications of Abscisic Acid CAS#21293-29-8

As an essential plant hormone, abscisic acid profoundly regulates physiological activities throughout plant growth and development. It promotes leaf fall, restrains overgrowth, and induces bud and seed dormancy. It also triggers stomatal closure, supports seed embryo formation, and strengthens plant tolerance to drought, low temperature and soil salinity. Thanks to these superior characteristics, abscisic acid is widely applied in agricultural production and ecological vegetation restoration.
