Quality Control

Our Cy7 Di Et is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and spectrophotometry for optical property validation. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring traceability and compliance with research-grade specifications. Custom purity grades and analytical services are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation and degradation. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture condensation. Keep away from strong oxidizing agents.
