Quality Control

Our N,n-Diethylspiro[2H-1-Benzopyran-2,3'-[3H]Naphtho[2,1-B]Pyran]-7-Amine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and spectrophotometric analysis to verify photochromic properties. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated 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 of the photochromic properties.
