Quality Control

Our 5-[4-(1-Methylethyl)Phenyl]-3-Isoxazolecarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and heavy metals. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and purity. Keep away from incompatible materials.
