Description

O,o-Di(Ethyl-D10) o-(2-Pyrazinyl) Phosphorothioate is a deuterated organophosphorus compound, specifically a labeled analog of a phosphorothioate insecticide. This high-purity, isotopically labeled standard is critical for ensuring analytical accuracy and traceability in advanced research and regulatory testing. It is primarily required by agrochemical research laboratories, environmental testing facilities, and analytical reference material producers for use in mass spectrometry, metabolism studies, and residue analysis.

Application

• Internal Standard for LC-MS/MS: Serves as a critical quantitative reference in liquid chromatography-tandem mass spectrometry for the accurate analysis of its non-deuterated counterpart and related metabolites.
• Metabolism and Pharmacokinetic Studies: Used as a tracer in ADME (Absorption, Distribution, Metabolism, and Excretion) research within agrochemical and pharmaceutical development.
• Environmental Fate Analysis: Enables precise tracking and quantification of pesticide degradation pathways and persistence in soil and water studies.
• Residue Testing and Method Development: Essential for developing and validating highly sensitive and selective analytical methods for regulatory compliance and food safety monitoring.
• Certified Reference Material (CRM) Production: Used as a key component in the formulation of certified analytical standards for quality control laboratories.

Quality Control

Our deuterated standards are produced under strict quality-controlled conditions to ensure exceptional isotopic purity and chemical stability. Each batch is characterized using advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and High-Resolution Mass Spectrometry (HRMS). A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98% D), chemical purity, and analytical results is provided with every shipment to support your compliance and research integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to maintain stability and purity.
