Description

Fipronil-Desulfinyl is a key metabolite and degradation product of the broad-spectrum insecticide Fipronil. This compound is of significant interest for analytical and environmental monitoring purposes, serving as a critical marker for the presence and breakdown of its parent compound. It is primarily utilized by agrochemical manufacturers, environmental testing laboratories, and research institutions involved in pesticide residue analysis, environmental fate studies, and the development of detection methods.

Application

• Analytical Reference Standard: Primary use as a certified standard for the accurate quantification of Fipronil and its metabolites in various matrices via HPLC, LC-MS/MS, or GC-MS.
• Environmental Monitoring: Critical for tracking the environmental degradation pathway and persistence of Fipronil in soil and water systems.
• Metabolite Studies: Essential in toxicological and pharmacokinetic research to understand the biotransformation and metabolic fate of Fipronil in target and non-target organisms.
• Quality Control & Method Development: Used by agrochemical producers and testing labs to validate analytical methods, ensure product quality, and monitor impurity profiles.
• Regulatory Compliance Testing: Supports testing for compliance with maximum residue limits (MRLs) set by global regulatory bodies (e.g., EPA, EFSA).
