Physical Properties
- Appearance: White to off-white crystalline powder, odorless.
- Melting Point: 250–255 °C (slight decomposition at upper limit).
- Boiling Point: Decomposes before boiling under normal pressure, no definite boiling point.
- Solubility: Practically insoluble in water, soluble in methanol, slightly soluble in ethanol, insoluble in non-polar solvents like n-hexane.
- Density: Approximately 1.35 g/cm3 (calculated).
- Optical Activity: No optical activity (racemic mixture).
- Moisture Absorption: Slightly hygroscopic, easy to absorb moisture in air.
Chemical Properties
- Chemical Category: Non-steroidal selective estrogen receptor modulator (SERM), with benzothiophene, phenol, ketone and piperidine groups.
- Stability: Stable under ambient temperature and pressure; incompatible with strong oxidants and strong acids.
- Acid-Base Property: Weakly acidic (phenolic hydroxyl groups); aqueous solution of hydrochloride is weakly acidic (pH ≈ 5.0–6.0).
- Hydrolysis: Stable under neutral/weakly acidic conditions; slow hydrolysis under strong alkali (pH > 10).
- Photostability: Light-sensitive, easy to discolor and decompose under direct sunlight/ultraviolet light.
- Reactivity: Phenolic hydroxyl groups undergo esterification/alkylation; ketone group undergoes reduction; piperidine group undergoes quaternization.
