Quality Control

Our Isoxazole, 4-Azido-5-Methyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high chemical purity and structural identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Due to its light-sensitive and potentially shock-sensitive azide functional group, handle and store with appropriate precautions, away from heat and incompatible materials.
