Quality Control

Our O,p-Xylene is produced under stringent 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 isomer composition, purity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, and we support compliance with global regulatory standards including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizers. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 15-25°C.
