1. Basic Information
Name: Diphenylacetonitrile
Alias: 2,2-Diphenylacetonitrile, Benzyl cyanide diphenyl derivative
CAS No.: 86-29-3
Molecular Formula: C14H11N
Molecular Weight: 193.24
2. Physical and Chemical Properties
Physical Properties
- Appearance: White or off-white crystalline solid
- Odor: Mild aromatic odor
- Solubility: Insoluble in water; soluble in ethanol, methanol, acetone, chloroform, toluene and other organic solvents; slightly soluble in hexane
- Melting Point: 73–75 °C
- Boiling Point: 300 °C (slight decomposition)
- Hygroscopicity: Non-hygroscopic under normal ambient humidity
- Crystal form: Flaky crystals recrystallized from ethanol
Chemical Properties
- Molecular structure: Two phenyl groups attached to the α-carbon of acetonitrile, containing cyano functional group (-CN)
- Cyano reactivity: Can undergo hydrolysis, alcoholysis, reduction and cyclization reactions to generate carboxylic acids, amides, amines and heterocyclic compounds
- Alpha-H activity: The hydrogen atom on the central carbon has strong activity, easy to carry out alkylation and condensation reactions under alkaline conditions
- Thermal stability: Stable below 200 °C; high temperature will cause partial decomposition and release cyanide-containing volatile substances
- Photostability: Stable under indoor light; avoid long-term strong UV irradiation to prevent slight discoloration
- Compatibility: Compatible with most anhydrous organic solvents; incompatible with strong oxidants, strong acid and strong reducing agents
3. Main Application Fields
1. Pharmaceutical Synthetic Intermediate (Core Application)
- Key building block for the synthesis of antihistamines, cardiovascular drugs and central nervous system APIs
- Raw material for manufacturing diphenyl acetic acid series pharmaceutical intermediates via cyano hydrolysis
2. Fine Chemical & Dye Intermediate
