Description

Alphaendosulfan D4 is a deuterium-labeled analog of the insecticide endosulfan, 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-based methods. It is a critical tool for researchers and quality control laboratories in the environmental monitoring, food safety, and agrochemical sectors who require precise measurement of endosulfan residues.

Application

• Internal standard for the quantitative analysis of endosulfan isomers (alpha and beta) via Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• Method development and validation in environmental testing laboratories for soil and water contamination studies.
• Residue analysis in food safety programs to monitor compliance with maximum residue limits (MRLs) for pesticides.
• Metabolic and pharmacokinetic studies in research institutions investigating the fate of endosulfan.
• Quality assurance and control in the manufacturing of agrochemical products.
• Calibration standard for analytical instrument performance verification.
