I was reading a similar question as mine here. But no one talked about nitrogen dioxide (NO2). Its boiling point is 21 °C, so it is easy to store. But how easy it is to handle compared to hydrogen peroxide or other oxidizers?
Are there any better liquid oxidizers that are relatively easy to use? At least, a combination of oxidizers or chemical stabilizers?
There certainly seems to be no near-safe liquid oxidizer; all require extreme care and handling. Is this an exception?
