Quality Control

Our Methylnaphthalene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including Gas Chromatography (GC) and other relevant methods. A Certificate of Analysis (COA) detailing purity, composition, and physical properties is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent evaporation and minimize moisture absorption.
