Description

O,o-Dimethyl Phosphorothionate-D6 Ammonium Salt is a high-purity, deuterium-labeled internal standard critical for advanced analytical quantification. This compound is essential for ensuring accuracy and reliability in mass spectrometry-based analyses, particularly for trace-level detection. It is primarily used by analytical laboratories, agrochemical researchers, and environmental testing facilities involved in method development and regulatory compliance for organophosphorus compounds.

Application

• Internal Standard for LC-MS/MS: Used as a deuterated surrogate for the accurate quantification of organophosphorus pesticides and their metabolites in complex matrices.
• Agrochemical Research & Development: Supports method development, validation, and metabolism studies for novel crop protection agents.
• Environmental Monitoring: Enables precise measurement of pesticide residues in water, soil, and food samples to meet stringent regulatory limits.
• Forensic & Clinical Toxicology: Assists in the definitive identification and quantification of toxic organophosphorus compounds in biological specimens.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in the analysis of phosphorothioate-related impurities in active pharmaceutical ingredients (APIs).
• Doping Control Analysis: Applied in sports anti-doping programs for the detection of prohibited performance-enhancing substances.
