Description

Terbufos-D10 (O,o-Diethyl-D10) is a deuterium-labeled isotopologue of the organophosphate insecticide Terbufos, specifically designed for use as an internal standard in advanced analytical chemistry. This high-purity compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in mass spectrometry, by correcting for variations in sample preparation and instrument response. It is a critical tool for researchers and quality control laboratories in the agrochemical, environmental monitoring, and food safety sectors who require definitive data for trace-level detection and quantification of Terbufos and its metabolites.

Application

• Internal Standard for Mass Spectrometry (MS): Primary application for precise quantification of Terbufos in LC-MS/MS and GC-MS methods, correcting for matrix effects and instrument drift.
• Environmental Analysis: Used in the testing of soil, water, and air samples for Terbufos residues to monitor environmental contamination and compliance.
• Agrochemical Research & Development: Serves as a critical reference material in metabolism studies, degradation pathway analysis, and the development of new analytical methods for pesticide formulations.
• Food Safety & Regulatory Testing: Enables accurate measurement of Terbufos pesticide residues in food commodities to ensure compliance with Maximum Residue Limits (MRLs) set by global authorities.
• Pharmacokinetic & Toxicological Studies: Employed in biomedical and toxicology research to track the absorption, distribution, metabolism, and excretion (ADME) of Terbufos in biological systems.
• Quality Control & Method Validation: Essential for validating analytical methods, conducting proficiency testing, and ensuring the accuracy of results in commercial testing laboratories.
