2-Methylbenzophenone

Description:

2-Methylbenzophenone, with the CAS number 131-58-8, is an organic compound that belongs to the class of ketones and is characterized by its structure, which consists of a benzophenone core with a methyl group attached to one of the aromatic rings. This compound typically appears as a white to pale yellow crystalline solid and is known for its aromatic odor. It is soluble in organic solvents such as ethanol and acetone but has limited solubility in water. 2-Methylbenzophenone is primarily used as a UV filter in various applications, including cosmetics, plastics, and coatings, due to its ability to absorb ultraviolet light and protect materials from photodegradation. Additionally, it has applications in the synthesis of other organic compounds and as a photoinitiator in polymerization processes. Safety data indicates that it should be handled with care, as it may cause skin and eye irritation upon contact. Proper safety measures, including the use of personal protective equipment, are recommended when working with this substance.

2-Methylbenzophenone

CAS: 131-58-8

2-Methylbenzophenone is a derivative of benzophenone that has been synthesized from a symmetrical molecule by the addition of two methyl groups on opposite sides of the benzene ring. The intramolecular hydrogen bonding in 2-methylbenzophenone allows for unsymmetrical molecules to form, which have a directional orientation. This makes 2-methylbenzophenone an excellent candidate for use in asymmetric synthesis. The reaction mechanism for the synthesis of 2-methylbenzophenone involves nucleophilic substitution with sodium carbonate and chlorine atom, followed by removal of the chloride ion with methyl ethyl ether or benzyl chloride. In this stepwise process, the first step is carried out at low temperature and then heated to increase the yield. The final step involves hydrogenation of the carbonyl group to form a keto group. Synthesis methods include condensation reactions, such as with sodium acetate and benzoic acid, or hydroly
