Quality Control

Our 1-Butyl Nitrite is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, ensuring reliability for critical industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Due to its highly volatile and light-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for extended periods to maintain stability. Keep container tightly sealed when not in use.
