Substance Name: Niacinamide [USP]
RN: 98-92-0
UNII: 25X51I8RD4
InChIKey: DFPAKSUCGFBDDF-UHFFFAOYSA-N

Note

  • 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.
