Quality Control

Our Benzoic Acid, 4-Hydroxy-2-Methyl-5-Nitro- (9Ci) is produced under a strict quality management system. We provide comprehensive analytical data to ensure batch-to-batch consistency and purity suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment 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). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider an inert atmosphere (nitrogen or argon) to maintain optimal purity.
