Quality Control

Our production of this high-purity photochromic compound adheres to stringent Good Manufacturing Practice (GMP) guidelines where applicable. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and spectrophotometry to verify photochromic performance. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and batch-to-batch consistency for your research and development needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature, handling and packaging should be conducted under subdued light or amber glass to prevent premature degradation or isomerization.
