茚三酮，一种三环1,2,3-三酮，是一种的有机铸造块。它是一种氨基酸试剂，能够显现多孔表面比如纸张，卡纸和原木上的指纹。 用途： 可用于多肽 ，氨基酸，氨基和氨基糖检测，能够和醛类以及伯胺产生强荧光三元化合物。和肌氨酸或脯氨酸反应生成甲亚胺叶立德。 茚三酮（水合茚三酮）可用作光度测定法和比色法定量氨基酸和多肽的试剂。它还可用于在二甲基亚砜中混合茚三酮与氢化茚三酮（茚三酮还原形式），制备茚三酮试剂。这种试剂可用于手动茚三酮法，定量氨基酸。 可以用于检测氨基酸，多肽和蛋白质中的自由氨基基团。 Used in the detection and assay of peptides, amino acids, amines, and amino sugars yielding highly fluorescent ternary compounds with aldehydes and primary amines. Reaction with sarcosine or proline gives azomethine ylides. Application： It can be used for the detection of peptides, amino acids, amino acids and amino sugars, and can produce strong fluorescent ternary compounds with aldehydes and primary amines. Reacts with sarcosine or proline to form methylimine Ylide. Ninhydrin (ninhydrin hydrate) can be used as a reagent for the determination of amino acids and peptides by photometry and colorimetry. It can also be used to prepare ninhydrin reagents by mixing ninhydrin with hydroninhydrin (reduced form of ninhydrin) in dimethyl sulfoxide. This reagent can be used for the manual ninhydrin method to quantify amino acids. It can be used to detect free amino groups in amino acids, peptides and proteins.
