Quality Control

Our 6-Chloro-4-Oxo-4H-Chromene-3-Carbaldehyde Oxime is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical quality attributes.

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 each use to prevent degradation from atmospheric moisture.
