-The detection was made employing the ALMA Band 4 Science Verification data of IRAS 16293–2422 around 146 and 157 GHz. The number of unblended to moderately blended lines appears to be sufficient.\\
+-Hydroxypropanal, also known as lactaldehyde, 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) and one with modest S/N between 32 and 138 GHz were unblended, three further transitions slightly blended. The authors provide column density raios of the C<sub>3</sub>H<sub>6</sub>O<sub>2</sub> isomers.\\
