Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide Certificates of Analysis (COA) with each batch, detailing purity, identity, and impurity profiles. Quality is assured through analytical methods including HPLC, IR spectroscopy, and titration to meet the specific requirements of dye and pigment manufacturers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
