Quality Control

Our 5-Methylsalicylic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying for moisture content, to ensure it meets exacting standards. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

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). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed when not in use to prevent degradation and absorption of moisture.
