Description

Propachlor Esa Sodium Salt is a high-purity sodium salt derivative of the herbicide propachlor, specifically its ethanesulfonic acid (ESA) metabolite. This compound is of significant importance as a key analytical reference standard and a crucial intermediate in environmental fate and metabolic studies. It is primarily needed by agrochemical research laboratories, environmental testing facilities, and manufacturers developing analytical methods for herbicide residue detection and monitoring.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantitative and qualitative analysis of propachlor ESA residues in environmental and biological matrices.
• Environmental Fate Studies: Critical for research investigating the degradation pathways, mobility, and persistence of the propachlor ESA metabolite in soil and water systems.
• Metabolite Identification & Profiling: Used in agrochemical R&D to study the metabolic breakdown of propachlor in plants and target organisms.
• Method Development & Validation: Essential for developing, calibrating, and validating advanced analytical methods such as LC-MS/MS and HPLC for regulatory compliance testing.
• Quality Control in Manufacturing: Serves as a benchmark for quality assurance in the production of related agrochemical products and metabolites.

Quality Control

Our Propachlor Esa Sodium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the stringent requirements for use as a reference material. A detailed Certificate of Analysis (COA) providing batch-specific results is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under dry, inert conditions to maintain stability and purity. Recommended long-term storage at 2-8°C.
