Quality Control

Every batch of 4-Cyano-3-Fluorophenyl 4-Butoxy-2-Fluorobenzoate is manufactured under strict quality management systems. We employ advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy to ensure identity, purity, and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing all critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
