Description

Metolachlor-D11 is a deuterated internal standard of the widely used chloroacetamide herbicide, Metolachlor, specifically labeled with eleven deuterium atoms. This high-purity analytical standard is critical for ensuring the accuracy and reliability of quantitative analysis in environmental and agricultural testing. It is primarily used by analytical laboratories, agrochemical manufacturers, and regulatory bodies for precise quantification of Metolachlor residues via mass spectrometry techniques such as LC-MS/MS and GC-MS.

Application

• Primary use as an internal standard for the accurate quantification of Metolachlor in complex matrices.
• Essential for residue analysis in environmental samples including soil, surface water, and groundwater.
• Critical component in food safety testing for monitoring pesticide residues in crops and food products.
• Used in metabolism and pharmacokinetic studies within agrochemical research and development.
• Supports regulatory compliance testing and method validation for EPA and other international standards.
• Enables high-precision isotope dilution mass spectrometry (IDMS) for definitive analytical results.

Quality Control

Every batch of Metolachlor-D11 is manufactured and analyzed to meet the stringent requirements for analytical reference standards. Our quality assurance includes rigorous testing for isotopic purity, chemical purity, and absence of interfering substances. Certificates of Analysis (COA) are provided, detailing results from NMR, HPLC, and MS analysis to confirm identity, purity, and isotopic enrichment. We adhere to ISO 17034 guidelines for reference material producers to ensure traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider storing under an inert atmosphere.
