Quality Control

Our production of 7-Oxabicyclo[4.1.0]hept-3-ene, 3-chloro- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and structural identity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for reliable, batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging. For long-term storage, consider maintaining under an inert atmosphere to preserve stability.
