Quality Control

Every batch of Benzenemethanol, α-Ethyl-4-Fluoro-, (Alphas)- (9Ci) is produced under strict quality management protocols. We employ advanced analytical techniques including chiral HPLC, GC, NMR, and MS to ensure identity, purity, and enantiomeric excess meet the stringent requirements of our clients. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment, and custom purity grades (e.g., >98%, >99%, >99.5%) are available to support your specific R&D or production needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
