Coumarin is an aromatic organic compound belonging to the benzopyrone class. Naturally found in tonka beans and cinnamon, coumarin has a sweet, vanilla-like scent and is widely used in fragrance, food, and pharmaceutical industries.
The melting point of coumarin is approximately 68–73°C. It appears as colorless crystals and should be stored in a cool, dry environment to maintain its stability.
The boiling point of coumarin is about 291°C. It is thermally stable under standard conditions and is often processed at lower temperatures to avoid degradation.
Coumarin uses span across multiple industries. It is used in perfumery, flavoring agents (in regulated amounts), and as a precursor in the synthesis of anticoagulant drugs such as warfarin. It also finds applications in laser dyes and optical brighteners.
Coumarin properties include being a colorless to white crystalline compound, having a distinct sweet odor, and being soluble in organic solvents like ethanol and ether. It has photoreactive and antioxidant characteristics, making it useful in chemical and pharmaceutical research.
