Used in perfumery for its warm, woody, and slightly sweet aroma, 9-Methymyrrhone enhances fragrance formulations, particularly in oriental, amber, and incense-type perfumes. It acts as a base note, providing depth and longevity to the scent. Due to its stability and tenacity, it is also employed in scented consumer products such as soaps, candles, and air fresheners to impart a rich, balsamic character. Its olfactory profile makes it valuable in creating natural-smelling accords in both fine and functional fragrances.
