Iminostilbene N-Carbonyl Chloride (CAS 33948-22-0) is a chemical compound whose specific physical and chemical properties dictate its utility and safe handling in various industrial applications, particularly within pharmaceutical synthesis.

The compound typically presents as a white to yellow powder. This visual characteristic is an important initial identifier for chemists and technicians. Its molecular formula is C15H10ClNO, with a molecular weight of 255.699 g/mol. These fundamental properties are essential for accurate stoichiometric calculations and reaction monitoring in chemical synthesis.

Key physical parameters provide further insight into its behavior. The melting point of Iminostilbene N-Carbonyl Chloride is reported to be between 149-153°C. This relatively high melting point suggests a stable solid form under ambient conditions. Its boiling point is considerably higher, around 413.7°C at 760 mmHg, indicating its thermal resilience during processes that might involve heating. Density is measured at approximately 1.3±0.1 g/cm³, a standard measurement for solid chemical substances. The flash point of 204.0±26.8°C and a low vapor pressure (0.0±1.0 mmHg at 25°C) suggest that while it requires careful handling due to its chemical reactivity, it has limited volatility at room temperature, which aids in safe handling protocols.

As a chemical intermediate, particularly for the synthesis of Carbamazepine, the purity of Iminostilbene N-Carbonyl Chloride is paramount. An assay purity of ≥95.0% is typically required, underscoring the need for meticulous manufacturing and quality control processes. This level of purity ensures that the subsequent reactions proceed efficiently and that the final drug product meets all necessary pharmaceutical standards.

Proper storage is also critical for maintaining the compound's integrity. It is recommended to store Iminostilbene N-Carbonyl Chloride in a cool, well-ventilated area. Packaging usually comes in 25 kg drums, but customized packaging options are often available from suppliers to cater to specific industrial requirements. When considering where to buy Iminostilbene N-Carbonyl Chloride, attention to these storage and packaging details is vital for ensuring product quality upon arrival.

In summary, the detailed physical and chemical properties of Iminostilbene N-Carbonyl Chloride are fundamental to its role as a key intermediate. Understanding these attributes is essential for its effective and safe use in pharmaceutical intermediate synthesis and other chemical applications.
