Quality Control

Our 4-(4-Aminophenoxy)Butanoic Acid is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to verify identity and purity against established specifications. Certificates of Analysis (COA) documenting all test results are provided as a standard commitment to transparency and quality assurance for our global B2B clients.

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 performance.
