Molecular Weight: 135.16
Synonyms: p-Aminoacetophenone, 1-(4-Aminophenyl)ethan-1-one
Product Category: Aromatic fine chemical, pharmaceutical intermediate, dye intermediate, analytical reagent
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Pale yellow to off-white crystalline powder
- Odor: Mild characteristic aromatic amine odor
- Solubility: Soluble in ethanol, methanol, ethyl acetate, hot water; slightly soluble in cold water; insoluble in alkanes and ether
- Melting Point: 104–106 °C
- Density (20 °C): 1.09 g/cm3
- Hygroscopicity: Slightly hygroscopic under high humidity
- Aqueous Stability: Stable under neutral and weakly acidic conditions; easily oxidized and darkened under alkaline, heating or long-term air exposure
Chemical Characteristics
- Molecular Structure: Benzene ring with para-position acetyl and amino functional groups
- Core Functional Mechanism: Dual reactive amino and carbonyl groups for condensation, diazotization, reduction and cyclization reactions; key building block for heterocyclic and drug skeletons
- Photostability: Light-sensitive; UV irradiation accelerates oxidation to form dark colored impurities
- Thermal Stability: Stable below 90 °C; high-temperature decomposition releases irritating aromatic amine fumes
- Chemical Compatibility: Compatible with polar organic solvents; incompatible with strong oxidants, concentrated strong alkalis and heavy metal salts
3. Main Application Fields
- Core Application: Pharmaceutical Synthetic Intermediate
