Indirect chiral separation methods based on enantiomeric derivatizations were developed in order to monitor optical purity of uncoded amino acids and a new series of amino acid derivatives. Marfey's reagent was used for derivatization of amino groups

Today's requirement for the transfer of information requires the use of broadband transmission systems. This need has successfully addressed the use of WDM systems, where the transmission of multiple channels should address the impacts of dispersion

The thermal behaviour of Selegiline (a chiral, non racemic pharmaceutical used in the therapy of Parkinson disease) was studied by differential scanning calorimetry (DSC) for determining the enantiomeric purity (e.p.) of the bulk substance. It has be

The enantiomers of chiral carboxylic acids were separated as their diastereomeric amides with (1R,2R)-(−)-1-(4-nitrophenyl)-2-amino-1,3-propanediol (“levobase”) and with “dextrobase” (the enantiomer of levobase) by high-performance liquid c
