Nicotinamide Uses

Niacinamide (CAS NO.98-92-0) is used as food additive, for multivitamin preparations and as intermediate for pharmaceuticals and cosmetics, it is also an inhibitor of sirtuins and has been reported to restore cognition in Alzheimer's Disease transgenic mice, also has been reported to be an effective skin whitener in topical application.

Nicotinamide Production

For production of niacinamide (CAS NO.98-92-0) in the past, methylethylpyridine was oxidized with nitric acid to yield niacin, and β-picoline was treated with air and ammonia to produce the nitrile that was then hydrolyzed to niacin-amide. A more modem process can produce both niacin and niacinamide (CAS NO.98-92-0) from a single feedstock, either β-picoline or 2-methyl-5-ethylpyridine by oxidative ammonolysis, a combination of oxidation and amination.
Either niacin or niacinamide (CAS NO.98-92-0) can be selectively isolated from the hydrolysis by varying the hydrolysis time and nitrite concentration. A higher hydrolysis temperature favors production of niacin.
