Quality Control

Our 1-[(Chloromethyl)Sulfonyl]Naphthalene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, impurity profile, and physical characteristics. Our quality commitment ensures the material meets the stringent requirements for use as a high-value intermediate in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases, oxidizing agents, and sources of ignition. Due to the reactive chloromethyl group, it is recommended to handle and store under an inert atmosphere for long-term stability.
