Uses

Used in Sunscreen and Cosmetic Products:
Methyl 3-[3-tert-butyl-4-hydroxy-5-(5-chloro-2H-benzotriazol-2-yl)phenyl]propionate is used as a UV-absorber in sunscreens and other cosmetic products to protect the skin from harmful UV radiation. Its ability to absorb and dissipate the sun's rays makes it an essential component in these products.
Used in Light Stabilizers:
methyl 3-[3-tert-butyl-4-hydroxy-5-(5-chloro-2H-benzotriazol-2-yl)phenyl]propionate is also used in light stabilizers, which are additives in various materials to prevent degradation caused by exposure to sunlight or other light sources. Its UV-absorbing capabilities help in maintaining the integrity and appearance of materials over time.
Used in Food Preservation:
As a derivative of propionic acid, methyl 3-[3-tert-butyl-4-hydroxy-5-(5-chloro-2H-benzotriazol-2-yl)phenyl]propionate can be used in food preservation to extend the shelf life of certain products by inhibiting the growth of mold and bacteria.

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.

Processes for the preparation of benzotriazole UV absorbers

Provided is a process for preparing 2H-benzotriazole UV absorbers containing a perfluoroalkyl moiety at the 5-position of the benzo ring, for example a trifluoromethyl group, which involves diazotizing the perfluoroalkyl substituted o-nitroaniline using concentrated sulfuric acid plus sodium nitrite or nitrosylsulfuric acid to form the corresponding monoazobenzene intermediate via the diazonium salt intermediate which is reduced to the corresponding 5-perfluoroalkyl substituted 2H-benzotriazole UV absorber compound by conventional reduction means. Also provided is a novel one-pot, multiphase reaction for the preparation of 2(2-nitrophenylazo) substituted phenols, which are precursors for 2H-benzotriazole UV absorbers.

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.

Isocyanuric acid derivative useful as a light stabilizer

Tris[2-hydroxy-3-(2,2,6,6-tetramethyl-4-piperidylamino)propyl] isocyanurate is useful as a light stabilizer for organic materials. A composition comprising an organic material and the isocyanurate is stable against light and also excellent in heat resistance. The isocyanurate can be produced by the reaction between tris(2,3-epoxypropyl) isocyanurate and 4-amino-2,2,6,6-tetramethylpiperidine.
