Ninhydrin (2,2-dihydroxyindane-1,3-dione) is an organic compound with the formula C 6 H 4 (CO) 2 C(OH) 2. It is used to detect ammonia and amines. Upon reaction with these amines, ninhydrin gets converted into deep blue or purple derivatives, which are called Ruhemann's purple.

Ninhydrin is a member of the class of indanones that is indane-1,3-dione bearing two additional hydroxy substituents at position 2. It has a role as a colour indicator and a human metabolite. It is a member of indanones, a beta-diketone, an aromatic ketone and a ketone hydrate.

The ninhydrin test is a chemical test which is used to check whether a given analyte contains amines or α-amino acids. In this test, ninhydrin (a chemical compound with the formula C 9 H 6 O 4 ; IUPAC name: 2,2-dihydroxyindane-1,3-dione) is added to a test solution of the analyte.

Ninhydrin is a chemical reagent used for detecting latent fingermarks on porous surfaces like paper. It reacts with the amino acid component of the fingermark deposit to produce a dark purple product known as Ruhemann’s purple.

May 19, 2022 · Ninhydrin test is used to detect the presence of amino acids in unknown samples. This test is also used in solid-phase peptide synthesis to monitor the protection for amino acid analysis of proteins. As the ninhydrin test is quite sensitive, …

Ninhydrin (synonym: 1,2,3-triketo-hydrindene hydrate) has been recognized since around the turn of the century as a reagent for detecting amino acids. However, it was not until the mid 1950’s that it was discovered ninhydrin could be used to develop latent prints on porous surfaces.

Mar 7, 2022 · Ninhydrin test is used by SSDs for residual protection detection on re-usable surgical instruments. Amino acids react with ninhydrin, which results in discoloration. Ninhydrin test is used in both quantitative and qualitative purposes – such as chromatographic visualization and peptide sequencing.

Ninhydrin test: Used to evaluate sudomotor or sympathetic nervous system function. It does not require a voluntary response from the client and therefore can be used for children or individuals with cognitive impairments.

Jun 21, 2023 · Ninhydrin, also known as 1,2,3-indention monohydrate, is an organic compound with the chemical formula C 9 H 6 O 4 ·H 2 O. It was first synthesized in 1910 by the Japanese chemist Siegfried Ruhemann and has since become a vital tool in various fields, including forensic science, analytical chemistry, and organic synthesis.

Ninhydrin, a tricyclic 1,2,3-trione, is a useful organic building block. It is an amino acid reagent, which reveals latent fingerprints on porous surfaces like paper, cardboard and raw wood. It is employed for nitrite detection in various samples, identifying contamination, and is also used as a colorimetric reagent.
