Molecular Formula: C6H13NO2
Molecular Weight: 131.17
2. Physical & Chemical Properties
Physical Properties
- Appearance: White crystalline powder, odorless
- Taste: Slightly sweet
- Solubility: Easily soluble in water; slightly soluble in hot ethanol; insoluble in cold ethanol, acetone, ether, aliphatic hydrocarbons
- Melting Point: Decomposes at 204–206 ℃, no clear melting point
- Specific Rotation: Racemic, no optical rotation
- Hygroscopy: Slightly hygroscopic under high humidity

Chemical Properties
- Molecular structure: Linear aliphatic amino acid, amino group at terminal C6, carboxyl group at C1, bifunctional monomer
- Amphoteric character: Contains amino and carboxyl groups, forms zwitterion in neutral water; generates soluble salts with acid/alkali
- Polycondensation: Self-polycondensation to produce nylon 6 monomer caprolactam via intramolecular dehydration cyclization; copolymerize with diacids/diols to make polyamide
- Esterification: Carboxyl reacts with alcohols to form amino acid ester derivatives
- Anti-fibrinolytic activity: Inhibit plasminogen activation, clinical hemostatic active structure
- Thermal stability: Stable below 180 ℃; high temperature cyclizes to caprolactam
- Compatibility: Compatible with water-soluble additives, buffer systems; avoid long-term contact with strong oxidants
3. Main Application Fields
