Quality Control

Our Ammonium,Ethyl(Meta-Hydroxyphenyl)Dimethyl-,Hydroxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by titration and identification by spectroscopic methods (IR, NMR), to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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 when not in use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
