Quality Control

Every batch of 4-Chloro-3-(2-Methylphenyl)Benzoic Acid is manufactured under strict quality management systems and undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our standard grade meets a typical purity specification of ≥97% (by HPLC), with specifications for residual solvents and related substances. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place 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 degradation from atmospheric moisture. Keep away from heat and incompatible materials.
