Understanding the chemical properties and ensuring the safe handling of chemical intermediates are paramount for their effective and responsible use. Ningbo Inno Pharmchem Co., Ltd. is committed to providing comprehensive information on Tetrachlorophthalic Anhydride (TCPA), including its key characteristics and safety guidelines.

Tetrachlorophthalic Anhydride, with its CAS number 117-08-8 and molecular formula C8Cl4O3, is classified as a cyclic dicarboxylic anhydride. Its chemical structure, featuring a phthalic anhydride core heavily substituted with chlorine atoms, dictates its reactivity and applications. It typically appears as a colorless needle crystal or powder, indicating a solid state under normal conditions. Its melting point, generally reported in the range of 255-257 °C, further confirms its solid nature at ambient temperatures.

From a reactivity standpoint, TCPA participates in typical anhydride reactions, such as nucleophilic attack by alcohols or amines to form esters or amides, respectively. The chlorine atoms on the aromatic ring also present opportunities for substitution reactions under specific conditions. These reactive sites are what make TCPA a valuable intermediate for synthesizing a wide array of organic compounds, including its significant use in flame retardants and as a precursor for dyes and pharmaceuticals.

When it comes to safety, like many chemical compounds, Tetrachlorophthalic Anhydride requires careful handling. Standard laboratory and industrial safety practices should be observed. This includes wearing appropriate personal protective equipment (PPE) such as gloves, eye protection, and protective clothing to avoid skin and eye contact. Adequate ventilation in work areas is essential to prevent inhalation of dust or vapors. It is also important to note its incompatibility with strong oxidizing agents, alcohols, amines, and bases, as reactions can be exothermic or produce hazardous byproducts.

Proper storage is also key to maintaining the integrity of TCPA. It should be stored in a cool, dry, and well-ventilated location, protected from direct sunlight and moisture, typically in tightly sealed containers. Adherence to these storage conditions helps prevent degradation and ensures the chemical remains suitable for its intended applications. Ningbo Inno Pharmchem Co., Ltd. emphasizes the importance of consulting Safety Data Sheets (SDS) for detailed, up-to-date safety information and handling procedures specific to Tetrachlorophthalic Anhydride.

By providing clear information on its chemical properties and safety protocols, Ningbo Inno Pharmchem Co., Ltd. aims to support the responsible and effective utilization of Tetrachlorophthalic Anhydride, ensuring both product quality and workplace safety for all our partners.
