CAS: 461-98-3
分子式: C6H9N3
分子量: 123.16

中文名稱: 4-氨基-2,6-二甲基嘧啶
                   6-氨基-2,4-二甲基嘧啶

英文名稱: 4-amino-2,6-dimethylpyrimidine
                   Kyanmethin
                   6-Amino-2,4-dimethylpyrimidine

性狀描述: 黃色針狀結晶。熔點191-192℃(183℃),升華,18℃時,1g能溶于0.64mg水及5.25g乙醇中。有氨的氣味。

生產方法: 乙腈與氨鈉反應:將乙腈加入干燥的高壓罐中,然后迅速加入氨鈉,在135-150℃,約0.8-1MPa壓力下反應1.5h,冷卻得粗環合物。粗品加熱水溶解。過濾,濾液濃縮得精制的產品。

用途: 醫藥中間體。用于生產磺胺二甲基異嘧啶,生產時,與對乙酰氨基苯磺酰氯(ASC)縮合,得6-對乙酰氨基苯磺酰氨基-2,4-二甲嘧啶,然后水解即得磺胺二甲基異嘧啶。
