Uses

Used in Sunscreen and Sunblock Production:
2',5-dichloro-2-(methylamino)benzophenone is used as a UV absorber for its capacity to absorb ultraviolet radiation, thereby providing protection against sun damage. It is particularly valued in sunscreen and sunblock formulas for its effectiveness in shielding the skin from the harmful effects of UV rays.
Used in Personal Care Products:
In the personal care industry, 2',5-dichloro-2-(methylamino)benzophenone is utilized as an ingredient in various products to offer sun protection. Its inclusion in these products is driven by the need to safeguard consumers from the risks associated with excessive UV exposure, such as skin aging and skin cancer.
Despite its widespread use, there is an ongoing debate regarding the potential health risks of 2',5-dichloro-2-(methylamino)benzophenone due to its absorption through the skin and possible harmful effects on human health. This has spurred research into alternative sun protection ingredients that can offer safety and efficacy without posing health risks, reflecting a growing trend towards safer and more sustainable ingredients in personal care and cosmetic products.

Transition-Metal-Free Synthesis of Acridones via Base-Mediated Intramolecular Oxidative C?H Amination

Intramolecular oxidative C?H amination of 2-aminobenzophenones was achieved in the presence of potassium tert-butoxide and dimethyl sulfoxide. A series of functionalized acridones were prepared in moderate to excellent yields in a mild, efficient, and transition-metal-free manner. (Figure presented.).

Preparation process of lormetazepam impurity

The invention belongs to the technical field of medicine synthesis and in particular relates to a preparation process of a lormetazepam impurity. The preparation process comprises the following steps: adding 2-amino-2',5-dichlorobenzophenone and potassium carbonate into a solvent; dropwise adding iodomethane and keeping heat and reacting; after reacting, carrying out post-treatment to obtain a lormetazepam impurity, wherein the post-treatment comprises the step of decompressing and evaporating to remove the solvent, adding purified water into restudies to dissolve residual salt, adding ethyl acetate to dissolve organic matters, separating out a water phase, concentrating an organic phase and crystallizing, and filtering to obtain the lormetazepam impurity. The solvent is THF (Tetrahydrofuran), DMF (Dimethyl Formamide) or DMSO (Dimethylsulfoxide). According to the preparation process, the 2-amino-2',5-dichlorobenzophenone is used as a raw material and the iodomethane is used as a methylation reagent; the target product impurity is obtained through one step of reaction, the conversion rate exceeds 98 percent and the yield exceeds 95 percent; a poisonous reagent is not used so that pollution to environment is reduced; meanwhile, less wastewater is reduced and the raw material is easy to obtain; compared with an existing process, the preparation process has great advantages.
