Dodecanal, also known as lauraldehyde or dodecyl aldehyde, is an organic compound with the chemical formula C ₁₂ H ₂₄ O or CH₃(CH₂)₁₀CHO. This colourless liquid is a component of many fragrances. It occurs naturally in citrus oils, but commercial samples are usually produced from dodecanol by dehydrogenation.^[2]
