Description

Thiofanox-Sulfon Pestanal is a high-purity analytical standard, supplied as a 100 mg unit, designed for precise calibration and quality control in analytical laboratories. This certified reference material is essential for ensuring the accuracy and reliability of pesticide residue analysis, particularly for the parent compound Thiofanox and its sulfon metabolite. It is primarily used by analytical chemists, quality assurance professionals, and researchers in environmental testing, food safety laboratories, and agrochemical development who require traceable and verifiable standards for method validation and regulatory compliance.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment (GC, LC-MS) and validating analytical methods for pesticide detection.
• Residue Analysis: Critical for quantifying residues of Thiofanox and its sulfon derivative in environmental samples (soil, water) and agricultural commodities to ensure compliance with MRLs (Maximum Residue Limits).
• Method Development & Validation: Serves as a key component in developing, optimizing, and verifying new chromatographic or spectroscopic analytical procedures in research settings.
• Quality Control (QC): Used in internal and external laboratory QC programs to monitor the performance and accuracy of analytical systems over time.
• Metabolite Studies: Enables specific study of the sulfon metabolite's behavior, persistence, and toxicity in environmental fate and metabolism research.
• Regulatory Compliance & Proficiency Testing: Provides a traceable benchmark for laboratories participating in accreditation audits and inter-laboratory comparison studies.

Quality Control

This Pestanal grade analytical standard is produced under stringent quality management systems to guarantee identity, purity, and stability. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) that provides lot-specific data including purity assay, chromatographic profile, and confirmatory identification. Our quality protocols are designed to meet the exacting requirements of GLP (Good Laboratory Practice) and ISO 17034 for reference material producers, ensuring reliability for your most critical analytical work.

Storage

Preserve in the original tightly closed container, protected from light. Store at 2-8°C. The product is hygroscopic (moisture-sensitive) and should be handled in a dry environment to maintain stability. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
