Our quality protocols are designed to meet the stringent requirements of R&D and process development applications, ensuring batch-to-batch consistency and reliability for your critical syntheses.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity, keep the container sealed and handle it in a moisture-free environment to prevent degradation.
