Quality Control

Our 3-(3-Carboxyphenyl)-5-Methoxybenzoic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting customer specifications and industry standards. Certificates of Analysis (COA) with complete batch traceability are provided and available 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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
