Quality Control

Our pharmaceutical-grade intermediate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for use in API synthesis. Certificates of Analysis (COA) documenting all test results are available upon request, supporting compliance with cGMP and ICH Q7 guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a dry environment and away from direct light exposure to maintain stability and potency.
