Quality Control

Our production of 2,5-Di(tert-Butylperoxy)-2,5-Dimethyl-3-Hexyne adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis, including assay by HPLC and verification of active oxygen content. Certificates of Analysis (COA) detailing purity, peroxide content, and key impurity profiles are provided and available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed, original container, protected from light and stored in a cool, well-ventilated area. Due to its nature as an organic peroxide and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) when in partially used containers. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Recommended storage temperature is below 30°C (86°F).
