Quality Control

Every batch of (2-Hydroxy-5-Methylphenyl)Triphenylphosphonium Bromide is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and commercial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
