Description

Methiocarb-D3 is a deuterated isotopologue of the carbamate pesticide methiocarb, specifically labeled with three deuterium atoms. This stable isotope-labeled compound is an essential analytical standard for accurate quantification and metabolic studies in environmental and food safety testing. It is primarily used by analytical laboratories and research institutions involved in pesticide residue analysis, method development, and quality control. The high chemical purity and isotopic enrichment ensure reliable performance as an internal standard in mass spectrometry-based techniques.

Application

• Used as an internal standard for the quantification of methiocarb residues via LC-MS/MS and GC-MS.
• Critical in method development and validation for pesticide analysis in compliance with global regulatory standards.
• Facilitates metabolism and degradation studies of methiocarb in environmental and biological matrices.
• Employed in quality assurance/quality control (QA/QC) programs for agricultural and food testing laboratories.
• Supports research on the environmental fate and transport of carbamate pesticides.
• Essential for dioxin and contaminant analysis laboratories requiring high-purity reference materials.

Quality Control

Every batch of Methiocarb-D3 is manufactured and analyzed under strict quality systems to ensure the highest standards of isotopic purity and chemical identity. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm deuterium incorporation and chemical purity. Certificates of Analysis (COA) detailing batch-specific results for assay, isotopic enrichment, and impurities are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability.
