Description

Diphacinone-D4 (Indanedione-4,5,6,7-D4) is a deuterium-labeled analog of the anticoagulant rodenticide diphacinone, specifically deuterated at the 4,5,6,7 positions of the indanedione ring. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring the highest accuracy and reliability in analytical measurements. It is primarily utilized by analytical laboratories, contract research organizations (CROs), and agrochemical manufacturers engaged in environmental monitoring, forensic toxicology, and metabolism studies.

Application

• Internal Standard for LC-MS/MS Analysis: Critical for the precise quantification of diphacinone and its metabolites in complex biological and environmental matrices.
• Environmental Fate and Residue Studies: Used in research to track the degradation, bioaccumulation, and environmental persistence of rodenticides.
• Forensic and Clinical Toxicology: Enables accurate identification and measurement of diphacinone in cases of suspected poisoning or exposure in humans and animals.
• Pharmaceutical and Agrochemical Metabolism Research: Serves as a tracer in ADME (Absorption, Distribution, Metabolism, and Excretion) studies to understand the metabolic pathways of anticoagulant compounds.
• Method Development and Validation: A key reagent for developing, optimizing, and validating robust analytical methods according to GLP and ISO 17025 standards.
• Quality Control and Reference Material: Used by manufacturers and regulatory bodies to certify and verify the purity and concentration of analytical standards and reference materials.
