Quality Control

Our [4-[[4-Anilino-1-Naphthyl][4-(Dimethylamino)Phenyl]Methylene]Cyclohexa-2,5-Dien-1-Ylidene]Dimethylammonium Acetate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets precise specifications for dye synthesis. Certificates of Analysis (COA) detailing all test results are provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
