5-硝基-2-丙氧基苯胺根据一般群众调查的结果,其度大约为蔗糖的4000倍,因此又称为P-4000,或者Ultrasüss(超级甜)。而通过科学方法用经过训练的品尝师进行检测的结果,其甜度约为2%蔗糖溶液的2300倍[3]

该物质是一种橙色的固体,微溶于水(136 mg·l−1[2]),在沸水及稀酸中稳定。由于该物质极甜,并且尝后无苦感[4],以及在沸水温度下稳定存在的特性,曾经作为一种人造甜味剂使用。由于它可能具有毒性,因此在许多国家已被禁止作为食品添加剂使用。

例如在美国,如果往食品中添加,或者存在可检出水平的5-硝基-2-丙氧基苯胺,会被认为掺假。这种行为违反了1950年1月19日美国联邦纪事文库中公开的一条法令(美国食品药品管理局条令,15 FR 321)。[5]
