Ninhydrin, 99%, Thermo Scientific Chemicals

Description

Ninhydrin is used for the determination of amino groups in amino acids, peptides and proteins. It finds application in forensic science for the analysis of latent fingerprints on porous surfaces such as paper. It is also used in thin layer chromatography (TLC) to monitor the progress of chemical reactions. In Kaiser test, it plays an important role to monitor the deprotection in solid phase peptide synthesis.

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.
