Quality Control

Our production of 1H-Indole-1-Carboxylic Acid, 2-Borono-5-(Methylthio)-, 1-(1,1-Dimethylethyl) Ester adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is fully characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, supporting your quality and regulatory documentation needs.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition.
