Nonadecane is a long-chain alkane used as a standard in gas chromatography and as a reference compound in analytical chemistry. It also serves as a building block in organic synthesis and, like other higher n-alkanes, as a feedstock for detergent production. It is a colorless, odorless solid at room temperature. Available in 1 g, 5 g, and 10 g quantities with purity ≥98.0% (GC). CAS: 629-92-5, Molecular formula: C19H40, Molecular weight: 268.52 g/mol. Store at ambient temperature. Signal word: Danger. Molekula supplies Nonadecane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
