N-n-Butylbenzenesulfonamide
1. Basic Information
Name: N-n-Butylbenzenesulfonamide
Alias: N-Butylbenzenesulfonamide
CAS No.: 3622-84-2
Molecular Formula: C10H15NO2S
Molecular Weight: 213.30
Category: Sulfonamide fine chemical intermediate, plasticizer additive, organic synthesis substrate, analytical raw material
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless to pale light yellow transparent oily liquid
- Odor: Mild faint sulfonyl characteristic odor
- Solubility: Miscible with ethanol, acetone, toluene, dichloromethane, ethyl acetate; slightly soluble in cold water
- Boiling Point: Decomposes above 300 °C under normal pressure
- Density (20 °C): 1.120–1.126 g/cm3
- Refractive Index nD20: 1.510–1.514
- Hygroscopy: Non-hygroscopic under normal storage conditions
- Aqueous property: Neutral sulfonamide compound, stable in neutral cold water at room temperature
Chemical Properties
- Molecular structure: Benzene ring linked with sulfonyl group, secondary amide structure connected with n-butyl alkyl chain
- Chemical reactivity: The N-H bond on sulfonamide can be alkylated, acylated to generate multi-substituted sulfonamide derivatives; benzene ring can undergo electrophilic substitution such as halogenation and nitration
- Thermal stability: Stable below 220 °C; long-time heating at high temperature will trigger partial decomposition and discoloration
- Photostability: Slightly light-sensitive; long-term direct ultraviolet irradiation gradually deepens liquid color
- Compatibility: Good compatibility with most resin, plastic and organic solvent systems; incompatible with concentrated strong acid and strong oxidants under heating
3. Main Application Fields
