At NINGBO INNO PHARMCHEM CO.,LTD., we believe in providing clear insights into the chemicals we offer. Sodium Dichloroisocyanurate (NaDCC) is a compound with distinctive chemical properties that lend it exceptional utility as a disinfectant and sanitizer. Understanding these fundamental characteristics helps explain its widespread adoption and effectiveness across various sectors. Exploring the chemical properties of NaDCC is key to appreciating its value.

The molecular formula of NaDCC is C3Cl2N3NaO3, and it is characterized by its high available chlorine content, typically around 60%. When dissolved in water, NaDCC undergoes hydrolysis, releasing hypochlorous acid (HOCl) and hypochlorite ions (OCl⁻). Hypochlorous acid is the primary active agent responsible for its potent antimicrobial activity. The reaction can be broadly represented as:

C₃Cl₂N₃O₃Na + 2H₂O → C₃H₃N₃O₃ (Cyanuric acid) + HOCl + Na⁺ + OCl⁻

This controlled release of active chlorine is a significant advantage. It provides a sustained disinfection action, which is particularly beneficial for applications requiring prolonged microbial control, such as in swimming pools or industrial water systems. The stability of NaDCC in its solid form also contributes to its overall advantage. It is less prone to degradation from light and heat compared to liquid chlorine compounds, leading to a longer shelf life and consistent performance. This stability is a major factor when discussing NaDCC disinfectant properties.

Furthermore, NaDCC solutions typically exhibit a pH in the neutral to slightly acidic range (around 5.5-7.0), which is considerably less corrosive and irritating than the highly alkaline solutions of sodium hypochlorite. This characteristic makes NaDCC safer to handle and less damaging to equipment and surfaces, including metals like stainless steel. For those interested in sodium dichloroisocyanurate for water treatment, this pH profile contributes to its efficacy and compatibility with water systems.

The combination of high chlorine content, stability, controlled release of HOCl, and a favorable pH profile makes NaDCC a highly effective and versatile disinfectant. Its numerous uses of NaDCC across different industries are a direct result of these advantageous chemical properties, solidifying its position as a go-to solution for disinfection and sanitization needs.
