产品介绍 Acetylacetone is an indicator for the complexometric titration of Fe(III). Used for the modification of guanidino groups in proteins (e.g. Arg) and amino groups in proteins.
别名 二乙酰基甲烷;2,4-戊二酮;间戊二酮;2,4-戊烷二酮;acac;Diacetylmethane;2,4-Pentanedione;acac
备注 产品 通常为烯醇式和酮式两种互变异构体的混合物,二者处于动态平衡中,烯醇式异构体在分子内形成氢键,混合物中,酮式约占18%,烯醇式占82%。将混合物的石油醚溶液冷却至-78℃,烯醇式就以固体形式析出,使二者分离;当烯醇式恢复室温,又自动处于上述平衡状态。
应用 An indicator for the complexometric titration of Fe(III)
