1. Basic Product Profile
- Full IUPAC Name: 1-deoxy-1-(methylamino)-D-glucitol
- Aliases: N-Methyl-D-glucamine, Methylglucamine
- CAS Number: 6284-40-8
- EINECS: 228-506-9
- Molecular Formula: C7H17NO5
- Molecular Weight: 195.21
- Chemical Classification: Polyhydroxy alkylamine, pharmaceutical excipient, contrast medium raw material, solubility booster, analytical reagent
- Core Advantages
Polyhydroxy chiral amine derived from D-glucose, with multiple hydroxyl groups and a secondary methylamino group. Excellent water solubility, strong ability to form soluble salts with acidic drugs, low toxicity and high biocompatibility. Widely used to prepare meglumine salt APIs (anti-inflammatory, contrast agents), solubilizer for poorly soluble pharmaceuticals, pH buffer stabilizer, and analytical chromatography additive.
2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: White crystalline powder
- Odor: Odorless
- Solubility: Freely soluble in water; soluble in hot methanol; slightly soluble in cold ethanol; insoluble in acetone, ether, hydrocarbons
- Melting Point: 128–132 °C
- Specific Optical Rotation [α]D20: -16.0° ~ -18.0° (c=10, water)
- pH (10% aqueous solution): 9.0–10.5 (weakly alkaline)
- Hygroscopy: Moderately hygroscopic, absorbs moisture in high humidity air
2.2 Chemical Properties
- Functional groups: 5 aliphatic hydroxyl groups + secondary methylamino group, chiral polyhydroxy amine structure
- Salt-forming characteristic: Secondary amine reacts with organic/inorganic acids to generate highly water-soluble meglumine salts (core application for contrast media & injectable drugs)
- Hydroxyl reactivity: Multiple -OH groups enable esterification, chelation with metal ions, strong hydrogen bonding for solubilization
- Thermal Stability: Stable below 110°C; prolonged heating above melting point triggers slight caramelization yellowing
- Acid & Alkali Stability: Stable in neutral/weak alkaline environment; concentrated strong acid heating causes sugar backbone hydrolysis
- Photostability: Slightly yellow after long-term intense UV irradiation
- Compatibility: Compatible with water-soluble pharmaceutical raw materials, polar solvents; incompatible with strong oxidants, concentrated mineral acids
3. Main Application Fields
3.1 Medical Contrast Medium Raw Material (Core Usage)
Synthesis precursor for iodinated X-ray contrast agents (meglumine diatrizoate, meglumine ioxitalamate); improves water solubility of iodine-containing contrast molecules for intravenous radiography.
3.2 Pharmaceutical Excipient & Drug Solubilizer
- Form meglumine salt with poorly water-soluble acidic active pharmaceutical ingredients (NSAIDs, antibiotics) to boost solubility for oral/injectable formulations;
- pH regulator and stabilizer for injection solutions, reduces irritation to blood vessels.
3.3 Analytical & Biochemical Reagent
- Mobile phase additive for ion-exchange chromatography;
- Chelating agent for trace metal detection experiments;
- Standard reference for sugar amine chiral analysis.
3.4 Fine Chemical Synthesis
Chiral polyol building block for asymmetric synthesis and water-soluble functional polymer preparation.
