Quality Control

Our N,N'-Dimethylquinacridone is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting industry and customer-specific standards. Comprehensive Certificates of Analysis (COA) detailing all quality parameters are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light sources to maintain stability and prevent degradation.
