Quality Control

Our 2-Thiophenecarboxylicacid,3-Amino-2,5-Dihydro-4-Methyl-,Methylester,1- CAS NO 125088-75-7 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance with cGMP and ISO standards for research and development use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). 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. Keep away from incompatible materials.
