This molecule is a fully saturated six-membered ring (piperidine) containing one nitrogen. The ring is numbered so that the nitrogen is position 1 and the carbons are 2, 3, 4, 5, and 6, closing back at N-1.
- At C-4 of the ring: there is a substituent that begins with two methylene units (-CH2-CH2-) leading to a tertiary nitrogen; this nitrogen bears two separate methyl groups, making it N,N-dimethyl.
- At N-1 of the ring: there is a carbon substituent that is (a) singly bonded to a hydroxyl group and (b) double-bonded to another nitrogen, which is positively charged (NH+). This positively charged nitrogen is also attached to a phenyl ring bearing a chlorine substituent at the para position and a trifluoromethyl (-CF3) group at the ortho position relative to the attachment point.
