+also report the detection of hydroxypropanone, also known as hydroxyacetone, in the course of a molecular line survey of this cold, shocked molecular cloud near Sagittarius B2 and in the Galactic center region. Several transitions with good signal-to-noise ratio (S/N) between 32 and 102 GHz were (essentially) unblended. The authors provide column density raios of the C<sub>3</sub>H<sub>6</sub>O<sub>2</sub> isomers.\\
