Quality Control

Our [4-[[4-[Bis(2-Hydroxyethyl)Amino]-o-Tolyl][4-(Dimethylamino)Phenyl]Methylene]Cyclohexa-2,5-Dien-1-Ylidene]Dimethylammonium Chloride is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with each shipment to guarantee it meets your technical 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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
