Used primarily as an intermediate in the synthesis of specialty chemicals, including plasticizers, lubricants, and surfactants. Its odd-numbered carbon chain makes it valuable in organic synthesis and biochemical research, particularly in metabolic studies to trace fatty acid pathways. Also employed in the production of fragrances and flavoring agents due to its fatty acid characteristics. In some cases, it serves as a reference standard in analytical chemistry for lipid profiling and mass spectrometry.
