HPLC Separation of Dicyandiamide, 1,2,4-Triazole, 3-Methylpyrazole on Primesep 100 Column Chromatogramm

High Performance Liquid Chromatography (HPLC) Method for Analysis of Dicyandiamide , 1,2,4-Triazole , 3-Methylpyrazole

Dicyandiamide, or cyanoguanidine, is used as a curing agent for epoxy resins. 1,2,4-triazole, is a heterocycle used primarily as an antifungal but has other uses in the pharmaceutical industry as well. 3-methylpyrazole is used in nitrogen fertilizers. All three compounds are structurally similar and can be separated in HPLC using Primesep 100 reverse-phase (RP) mixed-mode cation-exchange (CX) column using acetonitrile (ACN) and water mobile phase with phosphoric acid buffer and UV detected at 200 nm and 220 nm.
