Quality Control

Our production of 2-[(tert-Butyl)Azo]-2-Methylbutyronitrile adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for critical polymerization processes. Every lot is analyzed using advanced techniques including HPLC and NMR to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and solvent residues is provided with each shipment, supporting compliance with internal quality standards and customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its nature as an easily oxidized compound and a potential peroxide former, it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep away from heat, sparks, and incompatible materials. Always check the specific Safety Data Sheet (SDS) for detailed handling and storage instructions.
