Chiral discrimination and stereochemical characterization are essential for understanding the properties and applications of asymmetric compounds. Although chiral organoselenium chemistry has expanded significantly over the past decades, particularly in the field of asymmetric synthesis, reliable and broadly applicable analytical protocols for evaluating chirality in these compounds remain limited. In this way, this review summarizes progress over the past decade in analytical techniques applied to the study of chirality in organoselenium compounds, with emphasis on chiral recognition and enantiodiscrimination strategies. The discussion focuses on circular dichroism, chromatographic methods, NMR-based approaches, fluorescence-based sensing, and X-ray crystallography. These methodologies have enabled the assessment of qualitative and quantitative enantiomeric interactions in selected selenium-containing systems. Despite these advances, this review highlights current strategies to explore chiral selenium interactions as well as limitations in chiral recognition in organoselenium chemistry.

Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
