Quality Control

Our cis-Caronaldehydic Acid Hemiacetal is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee traceability and consistency for our customers' critical processes.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties.
