Description

Propachlor Esa Na-Salt, Pestanal is the sodium salt of the herbicide metabolite propachlor ESA (ethanesulfonic acid). This high-purity analytical standard is essential for environmental monitoring and regulatory compliance testing. It is primarily used by analytical laboratories, agrochemical manufacturers, and environmental testing agencies for the accurate quantification of propachlor residues in soil and water samples.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment and validating analytical methods (e.g., LC-MS, HPLC) in residue analysis.
• Environmental Fate Studies: Critical for tracking the degradation, mobility, and persistence of the herbicide propachlor in ecosystems.
• Method Development & Validation: Serves as a key component in developing and accrediting new testing protocols for regulatory bodies.
• Quality Control in Agrochemicals: Used by manufacturers to ensure batch consistency and monitor for metabolite impurities in technical-grade propachlor.
• Drinking Water & Soil Analysis: Enables precise detection and quantification of this major metabolite to ensure compliance with environmental safety limits.
• Research & Development: Supports academic and industrial research into herbicide metabolism, environmental impact, and remediation strategies.

Quality Control

As a Pestanal® analytical standard, this product is manufactured under stringent conditions to ensure the highest levels of purity and traceability required for critical laboratory work. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles. Our quality system ensures compliance with relevant standards for analytical reagents, providing the reliability needed for method validation and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment to prevent degradation and clumping.
