Quality Control

Our trans-2-Phenyl-2-Butene is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee consistent quality and traceability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
