Application: Derivatizing reagent for primary and secondary amines. Used in sequencing peptides by Edman degradation and in amino acid analyses by HPLC.
Application: 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.
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.
Packaging: One mL size packaged in flame sealed amber ampules under argon.
Ten mL size packaged in screw cap amber vials under argon.
