CAS 593-45-3: Octadecane

Description: Octadecane, with the CAS number 593-45-3, is a straight-chain alkane consisting of 18 carbon atoms and is part of the paraffin series. It is a colorless, odorless solid at room temperature, with a melting point typically around 28-30°C and a boiling point near 317°C. Octadecane is insoluble in water but soluble in organic solvents such as hexane and benzene. Its molecular formula is C18H38, and it exhibits a high degree of hydrophobicity due to its long hydrocarbon chain. Octadecane is commonly used in various applications, including as a phase change material in thermal energy storage, in the formulation of candles, and as a lubricant. Additionally, it serves as a standard in the study of hydrocarbon properties and behavior. Its relatively high molecular weight contributes to its stability and low reactivity under standard conditions, making it a useful compound in both industrial and laboratory settings.
