Observations of NGC6334I]]**\\
//Astrophys. J. Lett.// **965**, Art. No. L23 (2024).\\
Methoxyethanol, CH<sub>3</sub>OCH<sub>2</sub>CH<sub>2</sub>OH, was detected toward the high mass star-forming region NGC 6334I in archival ALMA Band 4 data around 131 and around 145 GHz. An excitation temperature of ~140 K was derived with a methoxymethanol to methoxyethanol ratio of ~30. The molecules was not detected in archival Band 7 data of IRAS 16293−2422B with a lower limt of this ratio of > 56.\\
