Quality Control

Our o-Phenylenediamine, 4-Nitro-, Conjugate Monoacid (8Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, handling and transfer should be minimized under direct light exposure.
