Quality Control

Our 2-(Trimethylsiloxy)-1,3-Butadiene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic analysis (NMR, IR), to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic (moisture-sensitive) nature, containers 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 flame.
