CAS 485-47-2: Ninhydrin

Description: Ninhydrin, with the CAS number 485-47-2, is an organic compound widely used in analytical chemistry, particularly for detecting amino acids and proteins. It appears as a yellow to brown crystalline solid and has a molecular formula of C9H6O4. Ninhydrin is known for its ability to react with primary and secondary amines, resulting in a colored complex, which is often purple or blue, making it a valuable tool in biochemical assays. This reaction is commonly utilized in fingerprint detection, as amino acids present in sweat can be visualized. Ninhydrin is soluble in organic solvents and has moderate solubility in water. It is important to handle ninhydrin with care, as it can be hazardous; it may cause skin and eye irritation and is considered a potential carcinogen. In addition to its applications in forensic science, ninhydrin is also used in the synthesis of various chemical compounds and in the study of protein structure and function.
