More than two dozen unblended or essentially unblended transitions were detected in several small recordings in Bands 6 and 7 through observations of the high-mass starforming region NGC 6334I-MM1. Assuming an excitation temperature of 200 K, its column density was found to be lower than that of methanol by a factor slightly larger than 30.

They analyzed the Cycle 0 ALMA science verification data and found methoxymethanol besides several other molecules.

They found methoxymethanol toward the low-mass proto-star IRAS 16293–2422 B in this context.
