Benzophenone dimethyl ketal(CAT: L047178) is a derivative of benzophenone where both carbonyl oxygen atoms are replaced with methoxy groups, forming a ketal structure. This compound is commonly used as a photoinitiator in polymerization processes, particularly in UV-curing applications for coatings, inks, and adhesives. The ketal structure makes it sensitive to light, allowing it to decompose upon exposure to UV radiation, generating reactive species that initiate polymerization. It can also serve as a synthetic intermediate in organic chemistry, where its ketal group can be hydrolyzed back to the parent benzophenone under acidic conditions. This makes it useful in controlled release and protection-deprotection strategies during synthesis.
