Quality Control

Our Dichloro(Phenyl)(4-Methylphenyl)Silane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and highly volatile. Keep away from strong acids, bases, and oxidizing agents. Use under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage or handling to prevent hydrolysis.
