Quality Control

Our 3-Methylpentane-2,3-Diol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality.
