Methyl acetate (CH₃COOCH₃) was identified by Tercero and co-workers in 2013 toward the Orion KL nebula. The data was drawn from an extensive survey acquired with the IRAM 30m telescope about a decade earlier. Multiple spin states were detected. While the detection has evidently not been confirmed, Müller states, "... a considerable number of transitions are not or only slightly blended, such that its detection can be considered secure in spite of many still unassigned lines."
