Quality Control

Every batch of 4,5-Dichloro-2-(1-oxopropyl)-3(2H)-pyridazinone is manufactured under a strict quality management system. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure compliance with exacting R&D and production standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
