However, the prep for a colonoscopy is another story. You may need to drink a lot of fluids, spend quite a bit of time in the bathroom and temporarily change your diet.
The mechanism of the Bamberger rearrangement proceeds from the monoprotonation of N-phenylhydroxylamine 1.N-protonation 2 is favored, but unproductive. O-protonation 3 can form the nitrenium ion 4, which can react with nucleophiles (H 2 O) to form the desired 4-aminophenol 5.
Routine use of colonoscopy screening varies globally. In the US, colonoscopy is a commonly recommended and widely utilized screening method for colorectal cancer, often beginning at age 45 or 50, depending on risk factors and guidelines from organizations like the American Cancer Society.

A score of 4 is given if the bowel preparation is inadequate, meaning that stool obscures the mucosa despite major washing/suctioning. The total score is calculated by adding up all 3 scores.
The three aminophenol isomers: Left: 2-Aminophenol (o-aminophenol) Center: 3-Aminophenol (m-aminophenol) Right: 4-Aminophenol (p-aminophenol) Aminophenol may refer to any of three isomeric chemical compounds: 2-Aminophenol; 3-Aminophenol; 4-Aminophenol; They are simultaneously an aniline and a phenol
Whole bowel irrigation is sometimes used prior to colonoscopy, bowel surgery, other abdominal/pelvic surgery, or a barium enema examination, to cleanse the intestines, enhancing visibility of the intestines' inner surfaces, preventing complications from occurring as a result of spillage of bowel contents into the abdominal cavity, and potentially providing other benefits depending on the type ...
