User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a nitrosamine that has butyl and 4-carboxybutyl substituents. It is the principal metabolite of the bladder carcinogen N-butyl-N-(4-hydroxybutyl)nitrosamine (BHBN-4). It has a role as a carcinogenic agent. It is a nitrosamine and a monocarboxylic acid. It derives from a N-butyl-N-(4-hydroxybutyl)nitrosamine.
