It has a characteristic pine aroma and is widely used in the fragrance and flavor industry. Pinene is known for its potential therapeutic properties, including anti-inflammatory and bronchodilator effects. In culinary applications, it contributes to the flavor profile of herbs and spices, enhancing sensory experiences. Its volatility makes it a key component in essential oils, contributing to the aroma of pine and other coniferous trees.
