Quality Control

Our Mesitylene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with industrial and reagent-grade standards to meet diverse application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
