An indicator for the complexometric titration of Fe(III) Acetylacetone is used as transition-metal chelating agent. |
| 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. |
| 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。 |
| 别名 | 乙酰丙酮;二乙酰基甲烷,2，4-戊二酮;Diacetylmethane;2,4-Pentanedione;acac |
