Chemical Structure

rac-Crotonoyl Chloride CAS 10487-71-5 chemical structure

Description

Structurally, rac-Crotonoyl Chloride (C4H5ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 104.53 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
