The enantioseparation of eighteen new chiral hydantoin derivatives was studied on three different polysaccharide type chiral stationary phases (CSP) Chiralpak AD, Chiralcel OD and Chiralcel OJ in the normal-phase HPLC mode. Chiralpak AD material exhibited the most universal chiral resolving ability and allowed the enantioseparation of 17 out of 18 compounds followed by Chiralcel OD (10 enantios...

The increasing demand for enantiopure drugs has led to the development of a variety of stereoselective separation technologies. Among them, high performance liquid chromatography (HPLC) is well recognized as a powerful, fast and efficient technique, which has been successfully employed for analysis and preparation of enantiomers of drugs. Nowadays, liquid chromatographic techniques are the focu...

The issue of drug chirality is attracting increasing attention among the scientific community. The phenomenon of chirality has been overlooked in environmental research (environmental occurrence, fate and toxicity) despite the great impact that chiral pharmacologically active compounds (cPACs) can provoke on ecosystems. The aim of this paper is to introduce the topic of chirality and its implic...

Since the turn of the twentieth century, it has been recognized that many drugs, agrochemicals, food additives and fragrances are chiral compounds and their chirality may considerably affect their bioactive behavior [1, 2]. The demand has been increasing for new analytical methods with high selectivity and efficiency. Chiral separation has become an attractive and important field in the separat...
