Is Niacinamide the same purchasing item as niacin or nicotinic acid?

No. Niacinamide is nicotinamide, CAS 98-92-0. Niacin, also called nicotinic acid, is a different chemical substance with CAS 59-67-6. The names are related through vitamin B3 terminology but cannot be used interchangeably in specifications, COAs, labels or change-control records.

Does a Niacinamide grade for one application automatically meet another application standard?

No. Cosmetic, food, supplement and pharmacopeial applications can require different specifications, documentation and acceptance limits. The application, target market and required standard must be identified before qualification. A high assay result alone does not demonstrate that the offered material meets every applicable identity, impurity or documentary requirement.

Which points should be controlled when changing an established Niacinamide source?

Compare identity, assay, related substances, water or loss on drying, residue, colour and particle-size requirements where relevant, using the agreed methods. Then verify behaviour in the intended formulation or process. Change approval should be based on the specified acceptance criteria and the required supporting documents, not solely on CAS 98-92-0.

Niacinamide (Nicotinamide) CAS 98-92-0

Niacinamide (Nicotinamide, CAS 98-92-0, EC 202-713-4) is pyridine-3-carboxamide, the amide form associated with vitamin B3. It is distinct from niacin or nicotinic acid (CAS 59-67-6). Buyers may require cosmetic, food, supplement or pharmacopeial specifications depending on the intended use, but suitability for any standard must be confirmed for the offered grade. Request assay, identification, related-substance limits, water or loss on drying, particle-size information where relevant, packaging and current COA, TDS and SDS.
