Morphology

propyl + group

The meaning is directly compositional: it denotes a chemical 'group' that is 'propyl' (an organic substituent derived from propane). This follows standard, cross-linguistic chemistry naming patterns, so a learner who knows the constituent words can infer the MWE's meaning.

Etymology

The name propyl group comes from the molecule propane after one hydrogen is cut off, leaving a three-carbon piece that can 'attach' to other molecules. So, propyl group means 'a three-carbon piece from propane that joins to a larger molecule'.
