Quality Control

Our In1662 is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive electronic applications. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your R&D and quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent degradation. Keep the container tightly sealed in a desiccator for long-term storage.
