Quality Control

Our Methylaziridine is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We adhere to relevant industry standards and can support requirements for research and commercial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. 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 extended stability. Keep away from strong oxidizing agents and acids.
