UNSPSC 51191920: Niacinamide or nicotinamide

This classification denotes a b vitamin with the molecular formula C6H6N2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 25X51I8RD4, chemically known as pyridine, 3-carbamoyl- but generally known as niacinamide, which bears US NIH Compound Identifier 936. European Medicines Agency schedules Niacinamide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB20661. The term NICOTINAMIDE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 13, No. 12, 1959, List 3).

UNSPSC 51191920 Niacinamide or nicotinamide, a Commodity code, nominally covers a pharmaceutical or nutraceutical ingredient, but recent state and local procurement activity shows little alignment with that scope. The three most recent opportunities tagged to this code involve wastewater valve repair services and parts (Broward County, Florida), parenteral nutrition and intravenous solutions for correctional healthcare (Washington State Department of Corrections), and sodium bisulfite chemical supply for a municipal water treatment facility (City of Meriden, Connecticut). None of these procurements involve niacinamide or nicotinamide. The issuing bodies span county governments, state corrections departments, and municipal water authorities—different sectors and jurisdictions with no obvious commonality to the code's stated commodity.

Geographic activity is scattered: Florida, Washington, and Connecticut each show one recent opportunity, with response dates ranging from July 29 through October 7, 2026. The code shows little relevant recent activity tied to its nominal scope. The mismatch between the code's name and the work actually being solicited suggests that either the recent opportunities were miscategorized or the code is not actively used for niacinamide procurement under state and local contracts.
