Quality Control

Every batch of 1-Naphthalenecarbonyl Chloride, 3-Methyl- (9Ci) is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture ingress and decomposition.
