Used as a reference standard in analytical chemistry particularly in gas chromatography (GC). Serves as a component of wax formulations coatings and specialty lubricants. Used in research studies involving hydrocarbons surface chemistry and phase-change materials. Functions as a calibration compound for instrument performance testing.

The primary purpose of n-tricosane is to act as a reference hydrocarbon in laboratory analysis and research while also contributing to wax-based products where hydrophobicity lubrication or controlled melting properties are required.

n-Tricosane is a straight-chain saturated hydrocarbon (alkane) consisting of 23 carbon atoms. It is a waxy colorless to white solid at room temperature and is naturally found in petroleum plant waxes insect cuticular waxes and other natural materials.
