Quality Control

Our (5-Methyl-2-Oxo-2,3-Dihydro-1H-Indol-3-Yl)Acetic Acid is manufactured 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) with detailed specifications are provided for every shipment, supporting compliance with cGMP and ICH guidelines for pharmaceutical intermediates.

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.
