What are the physical and chemical properties of 2-{2-[2-(2-Azidoethoxy)ethoxy]ethoxy}-1-[(4-methylphenyl)sulfonyl]ethanol (CAS: 168640-82-2)?

2-{2-[2-(2-Azidoethoxy)ethoxy]ethoxy}-1-[(4-methylphenyl)sulfonyl]ethanol is a colorless to slightly yellowish crystalline solid with a molecular weight of approximately 534.55 g/mol. It is poorly soluble in water but soluble in common organic solvents such as ethanol, methanol, and dimethyl sulfoxide. Chemically, it is highly reactive due to the azido group, making it susceptible to reduction and decomposition. It has a high melting point and is stable under normal conditions but requires careful handling due to its reactivity.
