Quality Control

Every batch of 1,3-Disilaindane is manufactured and tested under strict quality management protocols to ensure consistency and reliability for critical applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, supported by analytical techniques including GC, NMR, and HPLC. Our quality commitment aligns with ISO 9001 standards, and we support customer-specific qualification requirements for semiconductor and pharmaceutical applications.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flames.
