Coumarin

Description:

Coumarin, with the CAS number 91-64-5, is a fragrant organic compound belonging to the class of benzopyrones. It is a colorless crystalline solid that exhibits a sweet, vanilla-like aroma, making it popular in the fragrance and flavoring industries. Coumarin is soluble in organic solvents such as ethanol and ether but has limited solubility in water. Its chemical structure features a fused benzene and α-pyrone ring, contributing to its diverse biological activities. Coumarin is known for its anticoagulant properties and has been studied for its potential therapeutic effects, including anti-inflammatory and antioxidant activities. However, it is important to note that coumarin can be toxic in high doses and is regulated in some countries due to its potential hepatotoxicity. In addition to its applications in perfumery and food, coumarin is also used in the synthesis of various pharmaceuticals and agrochemicals. Overall, coumarin is a versatile compound with significant industrial and medicinal relevance, though caution is warranted regarding its safety profile.

Coumarin

CAS: 91-64-5

Coumarin is an organic chemical compound, which is a naturally occurring substance found in various plants, including tonka beans, sweet clover, and cinnamon. Structurally, it is a benzopyrone, characterized by a benzene ring fused to a lactone. Coumarin acts primarily as an anticoagulant by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. This mode of action disrupts the coagulation cascade, reducing the blood’s ability to clot effectively.
