Quality Control

Every batch of our 2-Amino-5-(2-Methyl-1-Oxopropyl)-3-Thiophenecarboxylic Acid Methyl Ester is produced and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific R&D or production requirements.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
