🧪 Physical Properties

• Appearance: A white to pale yellow crystalline powder or solid at room temperature.
• Odor: Odorless.
• Solubility: Slightly soluble in cold water, but soluble in hot water and common organic solvents such as ethanol, dimethylformamide (DMF), and dimethyl sulfoxide (DMSO).
• Melting Point: Typically ranges between 290 °C and 300 °C (often decomposes before melting).

⚗️ Chemical Properties

• Chemical Formula: C₈H₄N₂O₂ (Molecular weight: ~160.13).
• CAS Number: 13287-73-5.
• Acidity/Basicity: Due to the presence of two phenolic hydroxyl (-OH) groups, it exhibits weak acidic properties and can react with strong bases to form salts.
• Reactivity & Decomposition: It is generally stable under normal conditions but strictly incompatible with strong oxidizing agents. When exposed to high heat or fire, it can decompose and release highly toxic and irritating fumes, including hydrogen cyanide (HCN), nitrogen oxides, and carbon monoxide.

🏭 Main Uses

• Phthalocyanine Synthesis: Serves as a crucial precursor and intermediate in the synthesis of specialized phthalocyanine pigments and dyes. The hydroxyl groups allow for further functionalization, enabling the creation of water-soluble or highly substituted phthalocyanines.
• Advanced Materials: Utilized as a monomer in the development of high-performance thermosetting resins, specifically phthalonitrile resins, which are prized for their exceptional thermal stability and mechanical strength.
• Chemical Intermediates: Applied as a versatile building block in fine organic synthesis and the manufacturing of specialized agrochemicals and pharmaceuticals.
