A simple, precise, accurate, robust chiral high‐performance liquid chromatographic (chiral HPLC) method was developed for estimation of ( S )‐piperidin‐3‐amine ( S ‐isomer) in ( R )‐piperidin‐3‐amine dihydrochloride ( R ‐AMP). As AMP is a high‐melting solid and nonchromophoric compound, development of a suitable chiral method is a challenging task. The proposed chiral HPLC‐UV method involves a precolumn derivatization technique with para toluene sulphonyl chloride (PTSC) in the presence of a base to introduce chromophore into analytes. It utilizes chiralpak AD‐H column with a simple mobile phase of 0.1% diethyl amine in ethanol with a 0.5 mL/min flow rate. Analytes were monitored by using a UV detector at 228 nm. The resolution between the two enantiomers was more than 4.0. The developed method was validated as per current International Conference on Harmonization (ICH) guidelines.
