Quality Control

Our Pht-Met-Otbu is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with products typically meeting specifications suitable for research and pharmaceutical intermediate applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every batch upon request.

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.
