Hypothetically, what would the immediate physiological effects of injecting disinfectant into your veins be?

Not a doctor or anyone who regularly gets injections, but I would imagine some kind of temperature sensation, followed by pain, tingling, potential numbness. Depending on what substance you use, you'd be giving your circulatory system severe chemical burns. Kidneys and liver would most likely shut down or be significantly impaired, and the brain, heart, and other organs would follow. I imagine it would be a massively painful experience, probably leading to death. Not sure how much brain and body function you'd have left if you managed to survive.
