Quality Control

Our 3-Methyl-2-Pentenedioic Acid Bis(Trimethylsilyl) Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent degradation. Keep away from heat, sparks, and open flame.
