Quality Control

Our 2-Hydroxy-5-Methylisophthalaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, and is supplied with a detailed Certificate of Analysis (COA). We adhere to cGMP principles where applicable, and our quality commitment ensures the material meets the stringent requirements for research and commercial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to light and tendency for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
