PRODUCT INTRODUCTION
description
Pyriproxyfen is an aromatic ether that consists of propylene glycol having a 2-pyridyl group at the O-1 position and a 4-phenoxyphenyl group at the O-3 position. It has a role as a juvenile hormone mimic. It is an aromatic ether and a member of pyridines. It is functionally related to a 4-phenoxyphenol.
