Quality Control

Our 2-(Dimethyl-Phenylethynyl-Silanyl)-5,6-Dipropyl-Biphenyl-3,4-Dicarboxylic Acid Dimethyl Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your R&D and quality assurance protocols.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
