三丙酮胺性状描述： 该品为白色或淡黄色粉末，熔点43℃，沸点205℃，比重0.92g/cm3，闪点92℃，能溶于丙酮，醇，醚和水。三丙酮胺本身的稳定性不好，一般在有空气存在下放置3~4天后，就会由原来的乳白色变为淡黄色甚至棕红色。放置时间越长，物料颜色越深。
三丙酮胺质量标准:
外观 浅黄色至棕红色熔融体
纯度 ≥97.0%（GC）
灰分 ≤0.10%
水分 ≤1.20%
三丙酮胺用途： 主要作为合成受阻胺类光稳定剂的母体。经它还原制得的2,2,6,6-四甲基-r-哌啶醇是制取新型高效光稳定剂770、GW-540(cas95733-09-8 [亚磷酸三(1,2,2,6,6-五甲基哌啶醇)酯])和HALS的重要原料，同时也是制取4-取代硫基-2,2,6,6-四甲基哌啶氨氧自由基化合物的重要中间体。
