Quality Control

Every batch of 2-Thiazolidinecarboxylic Acid, 3-(Chlorocarbonyl)-2-Methyl- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency for your critical synthetic applications. A Certificate of Analysis (COA) detailing specifications such as assay (by HPLC/NMR), impurity profile, and physical characteristics is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
