It's often referred to as refrigeration propane or dimethylmethane. Blends based on it are marketed by Enviro-Safe and Duracool. The most common for replacing R22 seems to be R433b or a variant of it.

In the US, it seems like most in HVAC are overly concerned about the safety issues, while elsewhere, it's widely used. But they don't seem to have any problem with all the lithium batteries in modern electronics. And go figure, R1234yf is flammable and turns into toxic gas when burned...
