Quality Control

Our In1620 is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity assessment and structural confirmation via NMR and Mass Spectrometry. A detailed Certificate of Analysis (COA) documenting identity, purity, and relevant physical data 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 a controlled room temperature (15-25°C). The compound is light-sensitive; prolonged exposure to light should be avoided to maintain stability. Keep the container sealed in a dry environment to prevent moisture absorption.
