Quality Control

Our Butanoic Acid, 2-Amino-4-(Thiocarboxy)-, (S)- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis, to ensure it meets the exacting standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and oxidation. Keep away from incompatible materials.
