Quality Control

Every batch of 2-(4-Hydroxyphenoxy)Benzoic Acid is produced and tested under strict quality management protocols. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC for purity and identity confirmation, is performed. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product integrity.

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, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which could affect product quality and stability.
