Quality Control

We maintain stringent quality control protocols for 3,5-Dichloro-1-Naphthoic Acid to ensure batch-to-batch consistency and reliability for your critical syntheses. Our standard grade typically meets a purity specification of ≥97% (by HPLC), with comprehensive testing for identity, residual solvents, and related substances. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, and we can support development projects with custom purity grades upon request.

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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
