Quality Control

Our Thiophene, 2-Ethyl-4-Ethynyl- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical characterization, including HPLC, GC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support development projects requiring material that meets research-grade or custom purity specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, well-ventilated place. Keep away from heat, sparks, and open flames. Due to its sensitivity, minimize exposure to air and moisture during handling.
