User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a butan-4-olide that is dihydrofuran-2(3H)-one substituted by a methyl group at position 5. It has been found in the urine samples of humans exposed to n-hexane. It has a role as a flavouring agent and a human xenobiotic metabolite.
Assistant: This is a molecule that fits your description: CC1CCC(=O)O1
