Quality Control

Our production of 3-Hydroxy-2-Naphthoyl-Ortho-Phenetidide adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. The material is characterized and tested against established in-house specifications, which typically include identity confirmation, assay (purity), and control of key impurities. A Certificate of Analysis (COA) detailing the results for each production lot is provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
