Quality Control

Our 3-Carboxy-4-Hydroxy-5-Methoxybenzaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and physical characteristics. Specifications can be tailored to meet specific research-grade or industrial-grade requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
