Quality Control

Our Benzaldehyde, 4-(1-Butynyl)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing including HPLC, GC, and NMR to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality systems are designed to support cGMP and ISO standards for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flame. Due to its sensitivity, allow the container to reach room temperature before opening to prevent moisture condensation.
