Nicotinamide is a white powder. (NTP, 1992)|Nicotinamide is a pyridinecarboxamide that is pyridine in which the hydrogen at position 3 is replaced by a carboxamide group. It has a role as an EC 2.4.2.30 (NAD(+) ADP-ribosyltransferase) inhibitor, a metabolite, a cofactor, an antioxidant, a neuroprotective agent, an EC 3.5.1.98 (histone deacetylase) inhibitor, an anti-inflammatory agent, a Sir2 inhibitor, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite, a human urinary metabolite and a geroprotector. It is a vitamin B3, a pyridinecarboxamide and a pyridine alkaloid. It derives from a nicotinic acid.|Mediatric is a DEA Schedule III controlled substance. Substances in the DEA Schedule III have a potential for abuse less than substances in Schedules I or II and abuse may lead to moderate or low physical dependence or high psychological dependence.|An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and pellagra. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.|Vitamin B refers to several water soluble vitamins often found together in foods, all of which are necessary for normal growth and metabolism, but none of which are synthesized in adequate amounts by humans. The common forms of vitamin B include vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine) and B12 (cyanocobalamin). Except for niacin (when given in high doses), there is no evidence that the other B vitamins, in physiologic or even super-physiologic high doses cause liver injury or jaundice. The major forms of vitamin B and selected other water soluble vitamins (biotin, pantothenic acid, choline) are discussed briefly in this record.|Niacinamide is the active form of vitamin B3 and a component of the coenzyme nicotinamide adenine dinucleotide (NAD). Niacinamide acts as a chemo- and radio-sensitizing agent by enhancing tumor blood flow, thereby reducing tumor hypoxia. This agent also inhibits poly(ADP-ribose) polymerases, enzymes involved in the rejoining of DNA strand breaks induced by radiation or chemotherapy.|An important compound functioning as a component of the coenzyme NAD.

Air and Water Reactions:Water soluble.
Reactive Group:Amides and Imides
Reactivity Profile:An amine and amide. Acts as a weak base in solution. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
Autoignition Temperature:480 °C
Physical Dangers:Dust explosion possible if in powder or granular form, mixed with air.
