Quality Control

Our O,O,o-Tris(4-Nitrophenyl) Thiophosphate is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), related substances, and physical characteristics are provided and available upon request. We adhere to relevant industry standards for high-purity chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber or opaque. For long-term storage, consider under an inert atmosphere to maintain optimal purity.
