Used as a phase change material (PCM) in thermal energy storage systems due to its high latent heat of fusion and suitable melting point around 28°C. Commonly applied in building insulation to regulate indoor temperatures by absorbing and releasing heat during day-night cycles. Also utilized in solar heating systems and temperature-controlled packaging for pharmaceuticals and food. Serves as a standard in gas chromatography and as a lubricant component in some industrial applications. Its chemical stability and low cost make it favorable for large-scale thermal management solutions.
