Description

trans-Siduron Pestanal 250 Mg is a high-purity analytical standard of the phenylurea herbicide, siduron. This compound is essential for precise analytical work, serving as a critical reference material for quality control, method validation, and environmental monitoring. It is primarily needed by analytical laboratories, agrochemical manufacturers, and regulatory bodies involved in pesticide residue analysis and research.

Application

• Analytical Reference Standard: Primary use as a certified reference material for calibrating instruments and validating analytical methods (e.g., HPLC, GC-MS).
• Quality Control & Assurance: Used by manufacturers to verify the purity and identity of siduron in technical-grade products and formulated herbicides.
• Environmental Analysis: Critical for detecting and quantifying siduron residues in soil, water, and crop samples to ensure regulatory compliance and environmental safety.
• Research & Development: Serves as a pure benchmark in studies investigating herbicide efficacy, degradation pathways, and environmental fate.
• Method Development: Essential for developing and optimizing new chromatographic or spectroscopic methods for phenylurea herbicides.
• Forensic and Regulatory Testing: Provides an authoritative standard for confirmatory testing in legal or compliance-related investigations.
