Quality Control

Our tert-Butyl 4-Hydroxy-3-Nitrobenzoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, impurities, and physical characteristics are provided with every shipment to guarantee batch-to-batch consistency and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); ensure containers are sealed after each use to minimize exposure to atmospheric moisture.
