Widely used in pharmaceuticals as a topical analgesic and anti-inflammatory agent, especially in creams and ointments for muscle pain, arthritis, and skin irritations. Acts as a counterirritant, creating a cooling sensation followed by mild warmth, which helps relieve discomfort. Commonly found in chest rubs and vapor inhalants to ease congestion and respiratory issues. Also utilized in the production of semisynthetic derivatives like camphor sulfonic acid, which serves as a chiral resolving agent in organic synthesis. Employed in the fragrance industry for its strong, penetrating odor in perfumes, soaps, and air fresheners. Historically used in celluloid and nitrocellulose formulations as a plasticizer, though this application has declined due to flammability concerns. Still used in some traditional and homeopathic remedies for its perceived therapeutic properties.
