Quality Control

Our Carboxynitrazo is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes results from HPLC, NMR, and other relevant analytical methods to verify compliance with customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture.
