Quality Control

Our production of 5-(5-Methylfuran-2-Yl)-1H-Pyrazole-3-Carboxylic Acid adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP standards for pharmaceutical applications and can tailor purity grades to meet specific project 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 to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
