Quality Control

Our 3-Ethoxyphenylisothiocyanate is manufactured under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, identity, and impurity profile.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
