The molecule is a cyclohexane (six fully saturated carbons) 1,3-disubstituted ring. At position 1, the ring bears a thio-methyl group, -S-CH3. At position 3, the ring is bonded to a secondary amine (-NH-). This nitrogen connects to a two-carbon linker (-CH2-CH2-), which in turn is bonded to a tertiary amine nitrogen. This tertiary nitrogen is directly attached to two ethyl groups (-CH2-CH3 and -CH2-CH3), making it a diethylamino group.
