Nicotinamide (NAM), also known as niacinamide, is a form of vitamin B3 found in food and used as a dietary supplement and medication. It is an amide of nicotinic acid.
Niacinamide readily hydrolyzes to free acid by heating it in acid or alkaline solution.
Nicotinamide is a building block (active component) of coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phopshate (NADP).
Niacinamide is a white solid, odorless, with a bitter taste.
Niacinamide is sold by food stores and pharmacies, in pure form or as tablets.
Can also be bought online.
The hydrolysis of nicotinonitrile yields niacinamide.
However, it's much cheaper to just buy the substance from sellers.
- Make 3-aminopyridine
- Make 2-chloronicotinonitril
- Food supplement
- Stabilizer for acetaldehyde
Niacinamide has low toxicity and is not irritant. Consumption of pure nicotinamide has minimal side effects. At high doses however, liver problems may occur. Normal doses are safe during pregnancy.
