Quality Control

Our 1,4-Butanediol, 2-Amino- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) are provided with every shipment, detailing results from tests such as assay, residual solvents, and related substances. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

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