Quality Control

Our Bromoacetylcellulose is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, degree of substitution (DS), and reactivity. Certificates of Analysis (COA) detailing specifications such as bromine content, moisture level, and solubility are provided with every shipment to guarantee compliance with your research or production requirements.

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 sealed to prevent degradation from atmospheric moisture.
