Description

Thiofanox D3 (n-Methyl D3) is a deuterium-labeled isotopologue of the carbamate insecticide Thiofanox, specifically designed for use as an internal standard in advanced analytical chemistry. This high-purity reference material is critical for ensuring the accuracy and reliability of quantitative mass spectrometry analyses, particularly in residue testing and environmental monitoring. It is an essential tool for analytical laboratories, regulatory bodies, and agrochemical research institutions requiring precise quantification of the parent compound. The product is supplied under the CAS registry number 74829-46-2.

Application

• Internal Standard for LC-MS/MS & GC-MS: Primary use as a quantitative reference standard in mass spectrometry for pesticide residue analysis in food, water, and soil.
• Metabolic & Environmental Fate Studies: Enables precise tracking and quantification of Thiofanox and its metabolites in complex biological and environmental matrices.
• Method Development & Validation: Serves as a critical component in developing, calibrating, and validating analytical methods to meet regulatory compliance (e.g., EU SANTE guidelines).
• Quality Control & Assurance: Used in laboratory QA/QC protocols to ensure the accuracy and precision of analytical results for the parent insecticide.
• Pharmaceutical Impurity Profiling: Potential application in tracing and quantifying related substances or degradants in pharmaceutical synthesis where similar chemical motifs are present.

Quality Control

Every batch of Thiofanox D3 (n-Methyl D3) is produced and analyzed under strict quality management protocols to ensure the highest isotopic and chemical purity required for trace analysis. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to confirm isotopic enrichment and chemical identity. Certificates of Analysis (COA) are provided with each shipment, detailing batch-specific results for purity, isotopic abundance, and solvent content.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry, well-ventilated area. Keep the container sealed to prevent moisture absorption and potential degradation.
