Quality Control

Our n-(4-Hydroxyphenyl)-Maleamic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets stringent specifications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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. For long-term storage, consider using an inert atmosphere to minimize oxidation.
