Quality Control

Our 3-Phenylisoxazole-5-Carboxaldehyde 97% is manufactured under strict quality management protocols. Each batch is analyzed to confirm identity, purity, and consistency, meeting the high standards required for research and development applications. Certificates of Analysis (COA) detailing specific test results are provided with every shipment and are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize degradation. Keep away from heat and incompatible materials.
