Quality Control

Our production of 5-(1,5-Dimethyl-1H-Pyrazol-4-Yl)-3-Isoxazolecarboxylic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP (current Good Manufacturing Practice) standards for pharmaceutical applications.

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). The compound may be hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and purity.
