Prohexadione-Calcium (Pro-Ca, prohexadione-Ca or BX-112) is a plant growth retardant which is used to inhibit gibberellin biosynthesis of plants. It generally reduces shoot elongation in plants.
Prohexadione Calcium is a plant growth regulator.
Prohexadione calcium is plant growth regulator.
The industrial synthesis of prohexadione-calcium begins with the preparation of a substituted cyclohexane dione intermediate. This is typically achieved by condensing ethyl acetoacetate with methyl vinyl ketone under basic conditions to form the cyclohexenone ring. The resulting keto acid is then oxidized to introduce the carboxyl and hydroxyl groups at specific positions on the ring. The final step involves neutralizing the acid with calcium hydroxide to form the stable calcium salt. These reactions are carried out in aqueous or mixed solvent systems under controlled temperature and pH to ensure high yield and purity.
ChEBI: Prohexadione-calcium is a calcium salt containing equal numbers of prohexadione(2-) and Ca(2+) ions. A plant growth regulator, it is used as an anti-lodging agent in small-grain cereals. It has a role as a plant growth regulator, an agrochemical and a gibberellin biosynthesis inhibitor. It contains a prohexadione(2-).
Prohexadione calcium is used to inhibit foliar growth on apples and pears, reduces maturation of fruit and foliar covering. Also used on turf grass.
