Ortho-phenylphenol (OPP, or 2-phenylphenol) and its water-soluble salt, sodium ortho-phenylphenate (SOPP), are antimicrobial agents used as bacteriostats, fungicides, and sanitizers. Both have been used in agriculture to control fungal and bacterial growth on stored crops, such as fruits and vegetables.
