Understanding the fundamental properties and correct handling procedures for chemical compounds is paramount for both laboratory safety and successful synthesis outcomes. 1,2-Diiodobenzene, with CAS number 615-42-9, is a significant organic intermediate whose properties must be well-understood by chemists. NINGBO INNO PHARMCHEM CO.,LTD., a reputable manufacturer and supplier, emphasizes the importance of this knowledge.

Physically, 1,2-diiodobenzene typically appears as a white crystalline powder. Its molecular formula is C6H4I2, and it has a molecular weight of approximately 329.91 g/mol. Key physical parameters include a boiling point of around 152°C at 15 mmHg and a melting point reported above 300°C. Its density is noted as 2.524 g/mL at 25°C, and its refractive index is 1.718. These characteristics are important for identification and for designing reaction conditions.

From a chemical stability perspective, 1,2-diiodobenzene is considered stable at room temperature in closed containers under normal storage and handling conditions. However, a critical characteristic to note is its light sensitivity. Exposure to light can degrade the compound over time, potentially affecting its purity and reactivity. Therefore, proper storage is essential. It is recommended to store 1,2-diiodobenzene in a cool, dry place, away from direct sunlight, ideally in amber glass containers or in a dark storage area, and often under refrigeration at around +4°C, as indicated by storage guidelines.

Handling 1,2-diiodobenzene requires adherence to standard laboratory safety protocols. As with many fine chemicals, it can be irritating to the skin, eyes, and respiratory tract. Therefore, it is advisable to wear appropriate personal protective equipment (PPE), including safety goggles, chemical-resistant gloves, and a lab coat. Work should ideally be conducted in a well-ventilated area or a fume hood to minimize inhalation exposure. For specific safety data and detailed handling instructions, consulting the Material Safety Data Sheet (MSDS) is always recommended.

For professionals looking to buy 1,2-diiodobenzene for their research or manufacturing needs, sourcing from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures that the product meets specified purity standards and that proper handling and storage information is readily available. Understanding these chemical properties and handling requirements is fundamental to successfully and safely utilizing this valuable organic intermediate in any chemical synthesis endeavor.
