As a key player in the realms of optoelectronics and pharmaceuticals, 9-Phenylcarbazole (CAS 1150-62-5) is characterized by a specific set of chemical properties and physical attributes that dictate its utility and handling requirements. Understanding these aspects is crucial for effective utilization and safe laboratory or industrial practices. This fine chemical, typically manufactured in China to high purity standards, offers a glimpse into the precise nature of advanced chemical intermediates.

Physically, 9-Phenylcarbazole is commonly described as a white to almost white crystalline powder. Its melting point is typically in the range of 95-97°C, indicating its solid state at room temperature. Chemically, its molecular formula is C18H13N, with a molecular weight of approximately 243.31 g/mol. The compound exhibits slight solubility in water but is generally soluble in common organic solvents, a characteristic that facilitates its use in various synthesis and formulation processes. Its vapor pressure is quite low, as indicated by values like 4.16E-07 mmHg at 25°C, suggesting low volatility.

From a safety perspective, 9-Phenylcarbazole is often categorized as an irritant. Hazard statements like R37/38 (irritating to respiratory system and skin) and R41 (risk of serious damage to eyes) are frequently associated with its handling. Consequently, appropriate safety precautions are essential. This includes wearing protective eyewear, such as safety goggles or a face shield, and suitable protective clothing, including gloves and lab coats. Ensuring adequate ventilation in the workspace is also recommended to minimize exposure to airborne particles. In case of contact with eyes, immediate rinsing with plenty of water and seeking medical advice is standard procedure, as highlighted by safety descriptions like S26 and S39.

For procurement purposes, buyers often look for suppliers who provide comprehensive safety data sheets (SDS) and certificates of analysis (COA) for 9-Phenylcarbazole. These documents offer detailed information on handling, storage, disposal, and specific batch quality, ensuring that users can work with the chemical safely and effectively. Whether used in the synthesis of advanced optoelectronic materials or as a vital pharmaceutical intermediate, a thorough understanding of 9-Phenylcarbazole's properties and safety protocols, often provided by leading Chinese manufacturers, is fundamental to successful and responsible application.
