resorcinol

phenolic compound used in the manufacture of resins, plastics, dyes, medicine, and numerous other organic chemical compounds. It is produced in large quantities by sulfonating benzene with fuming sulfuric acid and fusing the resulting benzenedisulfonic acid with caustic soda. Reaction with formaldehyde produces resins used to make rayon and nylon amenable to impregnation with rubber, and as adhesives.

In medicine it is used externally in ointments and lotions as an antifungal
