Quality Control

Our p-Acetylaminobenzoic Acid Sodium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets stringent specifications for pharmaceutical and research applications. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
