Description

Diethyl Phosphate-13C4 Sodium Salt is a stable isotope-labeled analog of diethyl phosphate, a key metabolite and biomarker for organophosphate pesticide exposure. This high-purity compound is essential for quantitative mass spectrometry, providing an internal standard for accurate and reliable analytical measurements. It is primarily used by analytical laboratories, contract research organizations (CROs), and agrochemical companies engaged in environmental monitoring, toxicology studies, and regulatory compliance testing.

Application

• Internal Standard for LC-MS/MS Analysis: Critical for the precise quantification of diethyl phosphate and related organophosphate metabolites in biological and environmental samples.
• Biomarker Research: Used in human biomonitoring studies to assess exposure levels to organophosphate pesticides and flame retardants.
• Environmental Fate Studies: Enables tracking and quantification of pesticide degradation products in soil and water samples.
• Toxicology and Metabolism Studies: Facilitates the investigation of the metabolic pathways and pharmacokinetics of organophosphate compounds.
• Method Development and Validation: Serves as a certified reference material for developing and validating robust analytical methods in accredited laboratories.
• Forensic Analysis: Supports investigations involving suspected pesticide poisoning or environmental contamination incidents.
