Description

Chlorpyrifos-Methyl D6 (Dimethyl D6) is a deuterium-labeled isotopologue of the organophosphate insecticide Chlorpyrifos-Methyl, specifically designed for use as an internal standard in analytical chemistry. This compound is essential for ensuring the accuracy and reliability of quantitative analysis, particularly in mass spectrometry, by correcting for variations in sample preparation and instrument response. It is a critical tool for researchers and quality control laboratories in the agrochemical, environmental monitoring, and food safety industries who require precise measurement of Chlorpyrifos-Methyl residues.

Application

• Internal Standard for Mass Spectrometry (MS): Primary application for accurate quantification of Chlorpyrifos-Methyl in complex matrices via LC-MS/MS or GC-MS.
• Environmental Analysis: Used in the trace-level detection and measurement of pesticide residues in soil, water, and air samples for regulatory compliance and environmental impact studies.
• Food Safety Testing: Critical for analyzing pesticide residues on crops, fruits, vegetables, and in food products to ensure compliance with Maximum Residue Limits (MRLs).
• Metabolite Studies: Employed in pharmacological and toxicological research to track the metabolism and degradation pathways of Chlorpyrifos-Methyl.
• Method Development & Validation: Serves as a stable, non-interfering reference compound for developing and validating new analytical methods in accredited laboratories.
• Quality Control in Manufacturing: Used by agrochemical manufacturers to ensure batch-to-batch consistency and purity of Chlorpyrifos-Methyl technical material or formulations.

Quality Control

Our deuterated standards are produced under strict quality protocols to ensure the highest isotopic purity and chemical stability. Each batch of Chlorpyrifos-Methyl D6 is characterized by advanced analytical techniques including NMR (for deuterium incorporation) and mass spectrometry. Certificates of Analysis (COA) are provided, detailing parameters such as chemical purity, isotopic enrichment, and solvent content. We support compliance with standards relevant to analytical reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the product label or COA. For long-term storage, keep desiccated to maintain stability. This material is compatible with strong acids and organic solvents but should be handled in a well-ventilated area using appropriate personal protective equipment.
