General description
Phenyl isothiocyanate belongs to the class of aromatic compounds with isothiocyanate groups. It is typically used as a precolumn derivatization agent for the formation of phenylthiocarbamyl amino acids for their subsequent determination using chromatography techniques.
Application
Derivatizing reagent for primary and secondary amines. Used in sequencing peptides by Edman degradation and in amino acid analyses by HPLC.
Phenyl isothiocyanate may be used in the polypeptide and protein sequencing at the subpicomole and subnanomole levels, respectively, by applying automated Edman chemistry followed by the analysis using high-performance liquid chromatography (HPLC) technique.
Packaging
