Usage

General Description

Methyl 3-[3-tert-butyl-4-hydroxy-5-(5-chloro-2H-benzotriazol-2-yl)phenyl]propionate is a chemical compound often used as a UV-absorber in sunscreens and other cosmetic products. It belongs to the family of benzotriazoles, which are commonly used as light stabilizers and UV absorbers. This specific compound provides protection against UV radiation by absorbing and dissipating the sun's harmful rays. The tert-butyl and chloro substituents in the molecule contribute to its UV-absorbing capabilities. Additionally, the presence of the methyl ester group indicates that it is a derivative of propionic acid, which is often used as a food preservative. Overall, this chemical is an important component in sun protection products and other applications where UV absorption is necessary.

Composition comprising pesticide and benzotriazole UV absorbers

The present invention relates to an agrochemical composition comprising pesticide and UV absorber. The invention furthermore relates to UV-absorbers and to the use thereof in agrochemical compositions. It moreover relates to a method of controlling phytopathogenic fungi and/or undesirable plant growth and/or undesirable insect or mite infestation and/or of regulating plant growth.

One-pot process for the preparation of 5-sulfonyl-substituted benzotriazoles UV absorbers

5-Sulfonyl substituted benzotriazole UV absorbers are prepared from the corresponding 5-chlorobenzotriazole in a two step, but one-pot process where the second step involves the oxidation of the non-isolated 5-thio substituted benzotriazole using sodium tungstate, hydrogen peroxide and formic acid. The 5-sulfonyl substituted benzotriazoles exhibit enhanced absorption in the near-visible range (over 350 nm) thus providing effective protection to substrates in this critical area of the spectrum.
