Quality Control

Every batch of Oxazole, 5-(1-Diazoethyl)-2,4-Dimethyl- (9Ci) is manufactured and tested under strict quality management protocols. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including NMR, HPLC, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer (typically -20°C to -10°C) under an inert atmosphere (e.g., nitrogen or argon) due to its light-sensitive and easily oxidized nature. Allow the container to reach ambient temperature before opening to prevent moisture condensation. Keep away from heat, sparks, and open flames.
