Quality Control

Our 4-Ethyl-3-Fluorophenol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing identity, purity, and impurity profiles to support your quality assurance and regulatory 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). Keep away from heat, sparks, and open flame. Due to its phenolic and light-sensitive nature, prolonged exposure to light or elevated temperatures should be avoided to maintain product integrity.
