Quality Control

Every batch of our triarylmethane dye is produced under a strict quality management system. We employ advanced analytical techniques including HPLC, UV-Vis spectroscopy, and titration to ensure high purity and consistent chromaticity. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical properties is provided with each shipment to guarantee it meets your specific application 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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance.
