Quality Control

Our Methanone, Cyclopentyl(2S)-2-Pyrrolidinyl- (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity suitable for research and development applications. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data (HPLC, GC, NMR) for each lot, confirming identity, purity, and enantiomeric excess.

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, and well-ventilated area. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
