Chemical Properties of Nicotinamide Riboside Chloride
Molecular Structure and Composition
Nicotinamide riboside chloride (NR chloride) is a nicotinamide derivative where a ribose sugar is bound to the nicotinamide ring through a glycosidic bond. The molecular formula for NR chloride is C11H15ClN2O5, and its molecular weight is approximately 290.7g/mol. Structurally, NR chloride consists of a pyridine ring (nicotinamide group) attached to a ribose moiety (a five-carbon sugar), with a chloride ion (Cl-) in the crystal lattice of the salt form. The chloride salt enhances the water solubility of NR, making it more bioavailable for absorption when consumed orally or administered in other forms.
The compound is typically synthesized in its salt form as nicotinamide riboside chloride, which is stable and soluble in water, ensuring its ease of use in pharmaceuticals, supplements, and biotechnology.

Production Process of Nicotinamide Riboside Chloride
The industrial production of nicotinamide riboside chloride involves several steps, starting with the synthesis of nicotinamide riboside (NR) and ending with the formation of the chloride salt. Below is an overview of the general production process:
1. Synthesis of Nicotinamide Riboside (NR)
The production process typically begins with the synthesis of nicotinamide riboside (NR), which is the parent compound of NR chloride. NR can be synthesized through chemical reactions or enzymatic processes, often starting from nicotinamide and ribose or ribose derivatives.
In the chemical synthesis route, nicotinamide is reacted with ribose or its derivatives under controlled conditions to form nicotinamide riboside. The reaction typically requires a catalyst or a suitable solvent to facilitate the glycosidic bond formation between the nicotinamide and ribose moieties.
2. Phosphorylation to Form Nicotinamide Riboside Monophosphate (NRP)
Once nicotinamide riboside is synthesized, the next step is phosphorylation to form nicotinamide riboside monophosphate (NRP). This can be achieved using chemical reagents like phosphorus oxychloride (POCl3) or through enzymatic methods that catalyze the attachment of a phosphate group to the ribose sugar. The monophosphate form of NR is biologically active and serves as the immediate precursor to NAD+ in human cells.
3. Conversion to Chloride Salt (NR Chloride)
The final step in the production process involves converting the nicotinamide riboside monophosphate into the chloride salt form. This is done by reacting the NRP with hydrochloric acid (HCl) or another chloride source, which introduces the chloride ion into the structure. The chloride salt improves the solubility of NR, making it easier to incorporate into supplements and pharmaceutical formulations.
Once the chloride salt is formed, the resulting product undergoes purification. Methods like recrystallization, column chromatography, or solvent extraction are used to isolate pure NR chloride. Quality control tests, including HPLC, mass spectrometry, and NMR, are performed to ensure the purity and identity of the compound.
4. Purification and Quality Control
Purification is crucial for removing any impurities, unreacted starting materials, or by-products that may have formed during synthesis. The purified NR chloride is then subjected to rigorous quality control to ensure consistency, potency, and purity.
