Quality Control

Our 2-Trimethylsiloxy-2-Butenoic Acid Trimethylsilyl Ester is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing including GC, HPLC, and NMR to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. 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. Recommended storage temperature is 2-8°C for long-term stability.
