Quality Control

Our n-tert-Butyl-5-propylthiophene-2-carboxamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and test results are provided and available upon request. We adhere to cGMP standards where applicable to support our clients in regulated industry segments.

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. Keep away from incompatible materials.
