Description

Thiofanox-Sulfoxide Pestanal 100 Mg is a high-purity analytical reference standard of the sulfoxide metabolite of the carbamate insecticide thiofanox. This compound is essential for precise analytical work, providing a reliable benchmark for method development, calibration, and quality control in residue analysis. It is primarily required by analytical laboratories, regulatory bodies, and agrochemical manufacturers engaged in environmental monitoring, food safety testing, and toxicology studies to ensure accurate detection and quantification of thiofanox residues and its metabolites.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating analytical instruments like GC-MS, LC-MS/MS, and HPLC in residue analysis.
• Environmental Monitoring: Detection and quantification of thiofanox and its degradation products in soil, water, and air samples.
• Food Safety & Residue Testing: Method development and validation for analyzing pesticide residues in agricultural commodities to ensure compliance with Maximum Residue Levels (MRLs).
• Metabolite Studies: Used in research to study the environmental fate, metabolic pathways, and degradation kinetics of thiofanox.
• Quality Control & Assurance: Serves as an in-house control standard for agrochemical manufacturers to verify the purity and consistency of their products and formulations.
• Regulatory Compliance & Proficiency Testing: Essential for laboratories participating in inter-laboratory comparison studies and audits to demonstrate analytical competency.

Quality Control

Our Pestanal grade analytical standards are produced under strict quality management systems to guarantee the highest levels of purity and traceability. Each batch undergoes comprehensive analysis using advanced techniques including HPLC, GC, and NMR to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided, containing batch-specific data on purity, analytical methods, and storage recommendations, ensuring full compliance with ISO/IEC 17025 principles for testing and calibration laboratories.

Storage

Preserve in the original tightly closed container, protected from all light exposure. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry conditions to prevent degradation. For long-term stability, consider storage under an inert atmosphere or in a desiccator.
