Abscisic Acid CAS 14375-45-2

Abscisic acid (ABA) is widely distributed in the plant kingdom, naturally occurring in plants such as Sycamore, birch, rose leaves, cabbage, potato, pea, lemon, and avocado. It inhibits seed germination, regulates bud dormancy, promotes abscission layer formation and organ senescence and abscission, and is one of the most widely distributed inhibitory substances found in plants. Its molecular formula is C15H20O4, its molecular weight is 264.31, its pKa is 4.5, it is sparingly soluble in water or benzene, but readily soluble in methanol, acetone, ethanol, ethyl acetate, or alkaline aqueous solutions.

Abscisic acid (ABA) inhibitors can promote the accumulation of storage substances in seeds and fruits, especially storage proteins and sugars. Applying ABA externally during the early stages of seed and fruit development can increase the yield of grain crops and fruit trees.

Abscisic acid should be sealed under argon gas, protected from light, and stored in a dry place at 0-4°C or -20°C.
