High purity meets USP/EP pharmacopoeia standards, applied in oral tablet formulations and cell biology laboratory research.
2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: Pale yellow crystalline powder
- Odor: Odorless
- Solubility: Freely soluble in ethanol, chloroform, DMSO; slightly soluble in water; insoluble in aliphatic alkanes
- Melting Point: 142–150 °C
- Specific Optical Rotation [α]D20: -121° ~ -132° (c=1, chloroform)
- Hygroscopy: Non-hygroscopic under dry storage conditions
- Optical Property: Exhibits characteristic UV absorption under ultraviolet light
2.2 Chemical Properties
- Polycyclic Alkaloid Skeleton: Contains multiple methoxy groups and acetylamide functional group that determine biological activity
- Acid & Alkali Stability: Stable under neutral and weak acidic environments; amide hydrolysis occurs under heating with strong alkaline solution
- Thermal Stability: Slow decomposition under long-term heating above 160 °C
- Photostability: Highly sensitive to UV irradiation; prolonged light exposure causes color darkening and impurity generation
- Compatibility: Compatible with neutral pharmaceutical excipients; incompatible with strong oxidants, concentrated alkalis and heavy metal salts
