Quality Control

Every batch of Benzaldehyde, 3-Bromo-5-Ethyl-4-Hydroxy- (9Ci) is produced and tested under stringent quality management protocols to ensure consistency and purity for research and development applications. Our products undergo rigorous analytical testing, including HPLC, NMR, and GC-MS, to verify identity and quantify purity. A comprehensive Certificate of Analysis (COA) detailing all test results 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 cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
