Description

Dimethoate-D6 (O,o-Dimethyl-D6) is a deuterium-labeled isotopologue of the organophosphate insecticide dimethoate, where six hydrogen atoms are replaced by deuterium. This compound is essential as a high-purity internal standard for the accurate quantification and confirmation of dimethoate residues in complex matrices using advanced analytical techniques like LC-MS/MS and GC-MS. It is critically needed by analytical laboratories, contract research organizations (CROs), and agrochemical manufacturers engaged in environmental monitoring, food safety testing, and metabolic studies to ensure regulatory compliance and data integrity.

Application

• Internal Standard for Mass Spectrometry: Primary use as a quantitative internal standard in LC-MS/MS and GC-MS analysis for dimethoate and its metabolites.
• Environmental Analysis: Trace-level detection and quantification of dimethoate residues in water, soil, and agricultural runoff samples.
• Food Safety & Residue Testing: Ensuring compliance with Maximum Residue Limits (MRLs) in fruits, vegetables, and other food commodities.
• Metabolic & Pharmacokinetic Studies: Tracing the absorption, distribution, metabolism, and excretion (ADME) of dimethoate in biological systems.
• Quality Control & Method Development: Used in the development and validation of robust analytical methods within agrochemical and pharmaceutical QC labs.
• Forensic & Regulatory Toxicology: Supporting investigations and compliance reporting for regulatory bodies worldwide.

Quality Control

Every batch of Dimethoate-D6 is manufactured and analyzed under strict quality protocols to ensure the highest isotopic and chemical purity required for sensitive analytical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed data on isotopic enrichment, chemical purity, and solvent content.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. The material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to prevent degradation.
