Description

Fenvalerate-D5 is a deuterium-labeled analog of the synthetic pyrethroid insecticide Fenvalerate, specifically designed for use as an internal standard in analytical chemistry. This high-purity compound is essential for ensuring the accuracy and reliability of quantitative analysis, particularly in mass spectrometry. It is a critical tool for researchers and quality control laboratories in the agrochemical, environmental monitoring, and food safety sectors who require precise measurement and traceability of Fenvalerate residues.

Application

• Internal Standard for LC-MS/MS and GC-MS: Primary use as a quantitative reference standard in the analysis of Fenvalerate and its metabolites.
• Agrochemical Research & Development: Used in metabolism studies, environmental fate studies, and residue analysis during pesticide development.
• Environmental Monitoring: Critical for the accurate quantification of Fenvalerate in soil, water, and sediment samples to assess contamination levels.
• Food Safety Testing: Enables precise measurement of pesticide residues on crops, fruits, and vegetables to ensure compliance with Maximum Residue Limits (MRLs).
• Clinical & Forensic Toxicology: Supports investigations into potential poisoning cases involving pyrethroid insecticides.
• Method Development & Validation: Serves as a stable isotope-labeled standard to develop, optimize, and validate new analytical protocols.
• Quality Control in Manufacturing: Used by producers of Fenvalerate technical material and formulations to verify product purity and consistency.
