Quality Control

Our 1,3-Di-n-Propyl-1,1,3,3-Tetramethyldisilazane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C to maximize shelf-life stability. Keep away from heat, sparks, and open flame.
