Butenafine is a synthetic antifungal compound belonging to the allylamine class, primarily used as an active pharmaceutical ingredient (API) in topical formulations for treating dermatophyte infections. It is effective against fungal skin conditions such as athlete's foot (tinea pedis), jock itch (tinea cruris), and ringworm (tinea corporis). Butenafine works by inhibiting squalene epoxidase, an enzyme essential for ergosterol biosynthesis in fungal cell membranes, thereby disrupting fungal cell growth and replication. This product is supplied as a yellow oil with high purity (97.5-100%), suitable for pharmaceutical manufacturing and research applications. Its broad-spectrum activity targets various dermatophytes and some yeasts, providing a versatile option in antifungal drug development.
