Quality Control

Our 1,1,1-Triethyl-3,3-Dimethyldisiloxane is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including GC, NMR, and Karl Fischer titration. A Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with each 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). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed after opening to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
