Poppers as in amyl/isobutyl nitrate. Officially used as video head cleaner and nail polish remover and room deodorizers. Unofficial use as a sex aid. Can I bring them with me while traveling? Will TSA confiscate them? The bottle is absolutely tiny. Just 10 mL worth.
Under FAA regulations, liquids with a 'flash point' below 60 degrees C/140 degrees F are considered "flammable" and may not generally be carried on a standard passenger aircraft.
Isobutyl nitrite has a flash point of around -23 degrees C/-10 degrees F, which places it not just in the "flammable" range, but well into the "highly flammable" range.
Thus transporting "Poppers" on a plane, in either carry-on or checked luggage, is illegal.
In many parts of the world Isopropyl nitrite is used for "Poppers" instead of Isobutyl nitrite (due to the latter being determined to be a carcinogen). Isopropyl nitrite has a higher flash point, however it is still classified as a flammable liquid, and whilst it is legal to transport it on a commercial aircraft (up to 1 liter per aircraft), it requires proper documentation and approval, so would still generally not be allowed in the form you are considering.
Specific to your reference and tag to the TSA, thus travel within the United States, here's the Transportation Security Administration view:
Carry On Bags: No
Checked Bags: No
For more prohibited items, please go to the 'What Can I Bring?' page.
The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
