Quality Control

Our (E)-4,4'-(Diazene-1,2-Diyl)Bis(2-Methylbenzoic Acid) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FT-IR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request. We support compliance with REACH and other global regulatory frameworks.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, handling should be conducted under subdued light or amber glass when appropriate.
