Quality Control

Our Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 2,3-Dimethyl-, (1R,2R,3S,4S)- (9Ci) is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chiral HPLC and NMR, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with full analytical data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from strong acids and oxidizing agents. Due to its sensitivity, allow the container to reach room temperature before opening to minimize moisture ingress.
