Quality Control

Our production of 1-(3,3-Dimethylbicyclo[2.2.1]hept-5-en-2-yl)-1-butanone adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and batch-to-batch consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We operate under a cGMP-compliant quality system suitable for advanced intermediate applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames.
