CAS 103-33-3: Azobenzene

Description: Azobenzene is an organic compound characterized by its distinctive azo group (-N=N-) connecting two phenyl rings. It is a yellow to orange crystalline solid at room temperature and is known for its ability to undergo reversible photoisomerization between its trans and cis forms upon exposure to ultraviolet or visible light. This property makes azobenzene a valuable compound in various applications, including photonic devices, molecular switches, and drug delivery systems. Azobenzene is relatively stable under ambient conditions but can decompose under extreme heat or in the presence of strong oxidizing agents. Its solubility varies in different solvents, being more soluble in organic solvents than in water. Additionally, azobenzene exhibits interesting thermal and photochemical properties, which have been extensively studied in the context of materials science and nanotechnology. Due to its potential environmental and health impacts, handling azobenzene requires caution, as it may pose risks if ingested or inhaled.
