Astrophys.// **706**, (2026) Art. No. A316.\\ 2-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.\\ \\ ---- Contributor(s): H. S. P.
