**硝酸氯**是大氣平流層中一種重要的氣體。它儲存著氯元素，加快臭氧的消耗。

它與金屬、金屬氯化物、醇、醚和多數有機化合物劇烈反應並可能爆炸。如果被加熱到分解溫度，它會釋放出有毒的 Cl2 和 NOx。

它的製備方法是 0°C 時一氧化二氯與五氧化二氮反應：

　
: ${\rm {\ Cl_{2}O+N_{2}O_{5}\rightarrow 2ClONO_{2}}}$

硝酸氯與鹵素或鹵素互化物反應可製備其他鹵素硝酸鹽，如硝酸氟。與高氯酸氟類似，鹵素硝酸鹽也能與烯烴發生加成反應：

　
: ${\rm {\ (CH_{3})_{2}C=CH_{2}+ClONO_{2}\rightarrow O_{2}NOC(CH_{3})_{2}CH_{2}Cl}}$

硝酸氯與金屬氯化物反應得到無水硝酸鹽：

　
: ${\rm {\ 4ClONO_{2}+TiCl_{4}\rightarrow Ti(NO_{3})_{4}+4Cl_{2}}}$
