Trichloroisocyanuric Acid (TCCA) is a chemical compound that plays a significant role in disinfection, sanitation, and oxidation across numerous industries. Understanding its chemical properties is fundamental for effective and safe application. As a professional chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing insights into the science behind the products we offer, helping our clients leverage the full potential of TCCA (CAS 87-90-1).

Chemical Structure and Composition:

TCCA is an organochlorine compound with the chemical formula C₃Cl₃N₃O₃. Structurally, it is a derivative of cyanuric acid where three chlorine atoms are bonded to the nitrogen atoms of the triazine ring. This molecular arrangement is key to its potent oxidizing and chlorinating capabilities. The molecule is stable under normal storage conditions, making it easier to handle and transport compared to chlorine gas.

Mechanism of Action: Disinfection and Oxidation:

When TCCA dissolves in water, it hydrolyzes to release hypochlorous acid (HOCl) and cyanuric acid. Hypochlorous acid is the active sanitizing agent. It works by oxidizing essential components of microbial cells, such as enzymes and cell membranes, leading to cell death. This broad-spectrum antimicrobial activity makes TCCA highly effective against bacteria, viruses, fungi, and algae.

• Oxidizing Power: TCCA is a strong oxidizing agent. This property is utilized not only for disinfection but also in applications like bleaching textiles and paper, and as a reagent in organic synthesis. The released active oxygen contributes to its effectiveness.
• Chlorinating Agent: The chlorine atoms in TCCA readily participate in chlorination reactions. This capability is harnessed in various chemical processes and for sanitation purposes, where chlorine acts as a powerful disinfectant.

Key Physicochemical Properties:

• Appearance: TCCA typically appears as a white crystalline powder, granules, or tablets.
• Odor: It has a characteristic mild chlorine-like odor.
• Solubility: TCCA is moderately soluble in water, with a solubility of about 1.2 g/100mL at 25°C. It is also soluble in some organic solvents.
• pH: A 1% aqueous solution of TCCA typically has a pH between 2.0 and 3.7, indicating its acidic nature in solution.
• Stability: While stable when dry, TCCA is hygroscopic (absorbs moisture) and can decompose in the presence of moisture or heat, releasing chlorine gas. Proper storage is crucial.
• Available Chlorine: TCCA is known for its high percentage of available chlorine, usually exceeding 90%. This directly correlates to its disinfection potential.

Safety Considerations:

Despite its benefits, TCCA is a strong oxidizer and can be hazardous if mishandled. It can intensify fires and react vigorously with combustible materials, reducing agents, and certain other chemicals. Proper handling procedures, including the use of personal protective equipment (PPE) and storage in cool, dry, well-ventilated areas, are essential. As a responsible supplier, we provide detailed safety data sheets (SDS) for our TCCA products.

Understanding these chemical properties allows users to optimize the application of TCCA, ensuring maximum efficacy while maintaining safety standards. For procurement needs, partnering with a knowledgeable TCCA manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive a high-quality product backed by scientific expertise.
