Quality Control

Our 3-Methylstyrene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with products typically meeting a purity of ≥99.0% (GC). A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay, identity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
