Randomized trial investigates acetone's role in hot cores, highlighting its importance in organic chemistry.

The aim is to study the presence and relationship of acetone and its precursor acetaldehyde in hot cores.
Conducted a line survey of acetone and acetaldehyde in 60 hot cores using ALMA 3 mm lines.
Calculated rotational temperatures and column densities using XCLASS software.
Analyzed spatial distributions and correlations between acetone and acetaldehyde.
Acetone detected in 15 hot cores with rotational temperatures between 89 to 176 K.
Column densities of acetone ranged from (0.9-24) × 1016 cm−2.
Strong correlation (r = 0.82) between column densities of acetone and acetaldehyde.

Zhang et al. (2026) studied this question.
