Description

Acetochlor Oa, Pestanal is a high-purity analytical standard of the acetochlor herbicide, specifically designed for quality control and research applications. This compound is critical for laboratories requiring precise and reliable reference materials for method development, validation, and regulatory compliance testing. It is primarily utilized by agrochemical manufacturers, environmental testing facilities, and academic research institutions focused on herbicide analysis and residue studies.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating instruments and validating analytical methods in compliance with ISO/IEC 17025 and GLP.
• Pesticide Residue Analysis: Essential for the accurate quantification of acetochlor residues in soil, water, and agricultural products using GC-MS, LC-MS/MS, and HPLC techniques.
• Quality Control (QC) in Manufacturing: Serves as a benchmark for purity assessment of technical-grade acetochlor produced for commercial herbicide formulations.
• Environmental Fate Studies: Used in research to study the degradation, metabolism, and leaching behavior of acetochlor in various ecosystems.
• Method Development & Validation: A key component for developing new, sensitive analytical protocols for herbicide detection in complex matrices.
• Regulatory Compliance & Proficiency Testing: Supports laboratories in meeting stringent regulatory requirements set by bodies like the EPA and EFSA through participation in inter-laboratory comparisons.

Quality Control

Every batch of Acetochlor Oa, Pestanal is manufactured and certified to meet the highest standards for analytical reference materials. Our quality assurance process includes rigorous testing via multiple orthogonal methods, including HPLC, GC, and spectroscopic techniques, to guarantee identity, purity, and stability. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing batch-specific results, traceability, and expiration date, ensuring compliance with GMP and ISO guidelines for reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This product is hygroscopic (moisture-sensitive) and should be handled under dry conditions to prevent degradation. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
