The analysis of the products through standard and chiral HPLC reveals the number of peaks corresponding to the different stereoisomers formed. The goal is to identify the peaks in both types of HPLC, leading to the conclusion that there are 2 peaks in standard HPLC and 3 peaks in chiral HPLC, indicating the presence of stereoisomers and their interactions with the chiral stationary phase."}
