Quality Control

Every batch of 6-Phthalazinecarbonylchloride(9Ci) is produced and tested under strict quality management protocols to ensure high purity and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles as determined by advanced analytical techniques.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
