Methoxyethanal, also known as methoxyacetaldehyde, was detected in the course of a molecular line survey of this cold, shocked molecular cloud near Sagittarius B2 and in the Galactic center region. Three transitions with good signal-to-noise ratio (S/N) between 35 and 50 GHz were essentially unblended, three further transitions were somewhat blended. The authors provide column density raios of the C<sub>3</sub>H<sub>6</sub>O<sub>2</sub> isomers.\\
