Ninhydrin (CAS 485-47-2) is the gold-standard colorimetric reagent for detecting primary and secondary amino acids, available at 99% purity. It produces a characteristic purple-blue color (Ruhemann's purple) with primary amines at 570 nm absorbance. S.Nihar Exports, an ISO 9001:2015 certified fine and specialty chemical supplier, provides Ninhydrin globally with a Certificate of Analysis (COA) for every shipment.
Chemical Profile and Detection Mechanism
Ninhydrin (CAS 485-47-2) functions as a colorimetric reagent for detecting primary and secondary amino acids. Its reaction with primary amines yields a characteristic purple-blue color, known as Ruhemann's purple, which is quantifiable at 570 nm absorbance. With alpha-amino acids, Ninhydrin provides a quantitative colorimetric response, enabling concentration measurement. This reagent is supplied at 99% purity, making it suitable for analytical and research-grade applications.
Key Applications
Ninhydrin is utilized across diverse analytical and research disciplines. Primary applications include amino acid analysis and quantification through techniques such as TLC and HPLC. In forensic science, Ninhydrin is applied for fingerprint development on porous surfaces. Pharmaceutical quality control departments use it for protein hydrolysate analysis and monitoring peptide synthesis. Additionally, it serves in clinical diagnostics for the identification of aminoacidopathies.
