Uses and synthesis of Paclobutrazol powder

Paclobutrazol powder is a kind of plant growth regulator, Paclobutrazol Raw Materials has the effects of delaying plant growth, inhibiting stem elongation, shortening internodes, promoting plant tillering, increasing plant resistance, and improving yield.

Paclobutrazol CAS 76738-62-0 Main dosage forms include wettable powder, suspension, and powder.

Applications / Functions of Paclobutrazol powder

• Paclobutrazol powder is an azole plant growth regulator, endogenous gibberellin biosynthesis inhibitor.Paclobutrazol powder has the function of inhibiting plant growth and shortening pitch.
• Paclobutrazol CAS 76738-62-0 is a new type of plant growth regulator, which can inhibit the production of gibberellin derivatives and reduce the division and elongation of plant cells.Paclobutrazol Raw Materials can be easily absorbed by roots, stems and leaves, and conduct through the xylem of the plant, and it also has a bactericidal effect. Paclobutrazol Raw Materials has a broad spectrum of activity on grasses, making plant stems stumpy at the internodes, reducing collapse and increasing yields.
• Paclobutrazol Raw Materials is a new type of plant growth regulator with high efficiency, low toxicity and broad-spectrum fungicide.

Physicochemical Property of Paclobutrazol powder

Paclobutrazol powder is a white crystalline solid. It is stable at 50℃ for 6 months, and the aqueous solution is stable at room temperature for more than 30d, and it is more stable to ultraviolet light.

Production methodprocess of Paclobutrazol powder

• Preparation method: 1,2,4-triazole and 1-chloro-3,3-dimethyl-2-butanone as raw materials, the synthesis of α-1,2,4-triazole-3,3-dimethyl-2-butanone, and then condensed with p-chlorobenzyl chloride to produce α-p-chlorobenzyl chloride-1,2,4-triazole-3,3-dimethyl-2-butanone, and then reduced with sodium borohydride to get Paclobutrazol Raw Materials .
• Preparation method II: p-chlorobenzaldehyde and 3,3-dimethyl-2-butanone were used as raw materials to produce the corresponding alkenone, which was hydrogenated, brominated, and reacted with 1,2,4-triazole, and then reduced with sodium borohydride to obtain Paclobutrazol CAS 76738-62-0.
• Preparation method three: 1-(p-chlorophenyl)-2-(1,2,4-triazol-1-yl)propanoyl chloride reacted with tert-butylmagnesium bromide, and then reduced with sodium borohydride to obtain Paclobutrazol powder.
