Phenyl isothiocyanate acts as a derivatizing reagent for primary and secondary amines. It is used in sequencing peptides by Edman degradation and in amino acid analyses by HPLC. It is used for derivatizing N-terminal amino acids of proteins for automated sequential analysis. It is a synthon for dithiadiazafulvalenes.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
