Tryptophan is an essential amino acid used in the synthesis of proteins. Tryptamine is structurally similar to tryptophan. Serotonin is a neurotransmitter derived from tryptophan. Dimethyltryptamine and 5-MeO-DMT are psychedelic substances derived from tryptamine. All the compounds have similar structures and can present difficulties to separation in reverse-phase HPLC. They can be separated using the Primesep 100 mixed-mode column in gradient analysis with acetonitrile (ACN) and water mobile phase with ammonium formate (AmFm) buffer, making the method MS-compatible. The amines can also be UV detected at 280nm.
