Quality Control

Every batch of Naphthalene, 1,2-Dimethyl-7-Nitro- (9Ci) is produced and analyzed under strict quality management protocols to ensure consistency and purity for demanding synthetic applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
