Quality Control

Our Ethylenebis(Isothiouronium Bromide) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as assay, moisture content, and heavy metals. Our quality commitment ensures the material meets the stringent requirements for use in pharmaceutical and fine chemical synthesis.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
