Quality Control

Our Dichloridophosphoric Acid 4-tert-Butylphenyl Ester is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chromatography and spectroscopy, to confirm identity and purity. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and properties as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and ensure product integrity. Keep away from heat, open flames, and incompatible materials.
