Description and Uses
2-phenylphenol(OPP) is a broad spectrum fungicide used to protect crops in storage. It is highly soluble in water, moderately voatile but is not expected to be persistent in the environment. OPP is more selective than other free phenols but does produce phytotoxic effects.
2-Phenylphenol is a agriculture fungicide and is no longer used as a food additive.
