Used in pharmaceuticals as a topical analgesic and anti-inflammatory agent, commonly found in creams and ointments for muscle pain, arthritis, and skin irritations. Acts as a counterirritant by stimulating nerve endings to produce a cooling or warming sensation, which helps reduce pain signals. Also utilized in cough suppressants and chest rubs due to its expectorant properties. In cosmetics, serves as a fragrance component and skin conditioning agent. Employed in the synthesis of other organic compounds, including certain pharmaceutical intermediates. Historically used in celluloid production and as a plasticizer in nitrocellulose lacquers, though such applications are now limited.
