Xanthinol nicotinate
1. Basic Information
Name: Xanthinol nicotinate
Alias: Xanthinol niacinate, 7-[2-Hydroxy-3-(methylamino)propyl]theophylline nicotinate salt
CAS No.: 437-74-1
Molecular Formula: C13H21N5O3·C6H5NO2 = C19H26N6O5
Molecular Weight: 418.46
Category: Peripheral vasodilator API, cardiovascular pharmaceutical raw material, circulation improvement drug intermediate
2. Physical and Chemical Properties
Physical Properties
- Appearance: White to off-white crystalline powder
- Odor: Slight characteristic nicotinic acid odor, bitter taste
- Solubility: Freely soluble in water, methanol; soluble in ethanol; slightly soluble in acetone; insoluble in ether, chloroform
- Melting Point: 137–141 ℃
- Density (predicted): 1.31 g/cm3
- Hygroscopy: Slightly hygroscopic under high humidity
- Aqueous property: Weakly acidic aqueous solution, stable within pH 4–7
Chemical Properties
- Molecular structure: Ionic salt compound formed by xanthinol (theophylline derivative with methylamino alcohol side chain) and nicotinic acid
- Salt dissociation: Dissociates into xanthinol cation and nicotinate anion when dissolved in water
- Amine characteristic: Secondary amino group can form salts with various organic/inorganic acids
- Thermal stability: Stable below 110 ℃; long-term heating above melting point leads to partial decomposition and nicotinic acid volatilization
- Photostability: Light-sensitive, long-term UV irradiation turns faint yellow
- Compatibility: Compatible with neutral aqueous buffer, low-carbon alcohols; incompatible with strong oxidants, concentrated strong alkali
3. Main Application Fields
