Quality Control

Every batch of 2-Cyclopentene-1-Thione, 5-(1,2-Propadienyl)- (9Ci) is produced and analyzed under strict quality management protocols to ensure consistency and purity for research applications. Our products undergo rigorous quality testing, including chromatographic and spectroscopic analysis, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your critical R&D work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of the allene and thione groups, prolonged exposure to air should be minimized. For long-term storage, consider an inert atmosphere.
