Nicotinamide riboside chloride
1. Basic Information
Name: Nicotinamide riboside chloride
Alias: NR-Cl, Nicotinamide β-D-riboside chloride
CAS No.: 23111-00-4
Molecular Formula: C??H??ClN?O?
Molecular Weight: 290.70
Category: NAD+ precursor nutritional raw material, health food additive, anti-aging cosmetic raw material, cell culture medium supplement, biochemistry research reagent
2. Physical and Chemical Properties
Physical Properties
- Appearance: White to off-white crystalline powder
- Odor: Odorless, slight mild bitter taste
- Solubility: Freely soluble in water; soluble in methanol; slightly soluble in ethanol; insoluble in acetone, ethyl acetate, petroleum ether
- Melting Point: Decomposes above 140 ℃ without distinct melting point
- Density (predicted): 1.42 g/cm3
- Hygroscopy: Moderately hygroscopic, easy to absorb moisture and agglomerate under high humidity
- Aqueous property: Weakly acidic aqueous solution, pH 3.5–5.0; prone to hydrolysis under high temperature and strong alkaline conditions
Chemical Properties
- Molecular structure: Nicotinamide linked to β-D-ribose via glycosidic bond, chloride ion as counterion; pyridine nitrogen positively charged, core precursor of intracellular NAD+, NADP+, NADH
- Glycosidic bond hydrolysis: High temperature, strong acid or strong alkali breaks riboside bond to generate nicotinamide and ribose, losing biological activity
- Light oxidation sensitivity: Pyridine ring is easily oxidized under UV light to form yellow degradation impurities, activity decreases sharply
- Thermal stability: Stable below 60 ℃; long-term heating above 80 ℃ accelerates hydrolysis and discoloration
- Metal ion catalyzed degradation: Heavy metal ions (Cu2?, Fe3?) accelerate oxidative decomposition
- Photostability: Extremely light-sensitive; must be stored away from light
- Compatibility: Compatible with neutral and weakly acidic carriers, trehalose, vitamin series; incompatible with strong alkali, strong oxidants, heavy metal salts
