Quality Control

Our 2-Methyl-1-Phenylpropene is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and at temperatures between 2°C and 8°C for long-term stability. Keep away from strong oxidizing agents.
