Quality Control

Our 1H-Indazole-5-Carboxaldehyde, 7-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical quality attributes. Our commitment to quality supports applications requiring high-purity building blocks under cGMP-like controls for non-GMP applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
