Overview
Fipronil (CAS 120068-37-3) is a phenylpyrazole-class compound supplied as a technical-grade active ingredient for the manufacturing of external-use veterinary formulations. It is valued for its stable activity profile, consistent physical properties, and reliable performance during formulation processes.
As a non-systemic active substance, Fipronil is commonly incorporated into topical preparations developed by veterinary pharmaceutical manufacturers. Its chemical stability, compatibility with various organic solvents, and low water solubility make it suitable for powders, external liquids, and other non-systemic formulation types.
We supply Fipronil as a controlled-quality raw material to support downstream formulation development and large-scale production.
