Nicotinamide, the amide form of Vitamin B3, is a white, crystalline powder that dissolves in water. In formulation work, maintaining a controlled assay and low moisture content helps ensure accurate dosing and stable dry blending in vitamin premixes, tablets, capsules, and fortified food systems.
The product specification identifies the material technically rather than describing it only as a general vitamin. It lists UV absorption at 261 nm, an absorbance ratio at 245 nm / 261 nm, a melting point of 128–131°C, and a pH range of 5.5–7.5 in a 100 g/L solution. Together, these controls support the evaluation of incoming materials and consistency between batches.
During storage, keep the product in its unopened original package, in a dry place at ≤25°C, and away from light.
