Quality Control

Every batch of Benzene, 1-[(1R)-1-Isothiocyanatoethyl]-4-Methoxy- (9Ci) is produced and analyzed under strict quality management protocols. We employ advanced analytical techniques, including chiral HPLC, to guarantee high enantiomeric purity and chemical identity. A comprehensive Certificate of Analysis (COA) detailing purity, chiral excess, and impurity profiles is provided with each shipment to ensure full traceability and compliance with your research or development specifications.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
