There is zero difference. Isopentyl and Isoamyl are both a 5 carbon branch and identical. The real name is Isopentyl Nitrite (CH3)2CH-CH2-CH2-) CAS 110-46-3 Isoamyl is an outdated term and not used. I am not sure why it would appear on any bottle.

AMYL RUSH did exist once. You would have to be now in your mid to late 80s to have ever seen that. Hassing (Locker Room) replaced it with BUTYL, then Rush Brands in San Fransisco followed the lead. Poppers today do not contain amyl, whether they be Rush, Jungle, Amsterdam or whatever. You say that you wonder why an easily misumderstood name like isoamyl would appear on a bottle? I can think of one very good reason, the same reason that many newbie manufacturers put the word AMYL in the brand! This is because people wrongly think the poppers from their youth were amyl, they were not, they were butyl. I accept that there might be a few guys in their late 80s who might have been around for the very short period that Rush contained amyl. The same goes for UK, because PWD Rush were the biggest there in the 1980 period, not Jungle Juice (which was amyl then).
