Basic Information

Structural Information

• Structure Type: Chiral amino acid salt, essential amino acid derivative
• Structural Features: Contains one chiral carbon atom, two amino groups and one carboxyl group. Formed by L-Lysine reacting with hydrochloric acid, presenting good water solubility and stable crystal structure.

Physical & Chemical Properties

• Appearance: White crystalline powder or colourless transparent crystal
• Odor: Odorless, slightly salty taste
• Melting Point: 263–264 °C (decomposition)
• Specific Rotation: +19.0° ~ +23.0° (c=8, Water)
• pH Value (10% Aqueous Solution): 5.0 ~ 6.0
• Solubility: Freely soluble in water; slightly soluble in ethanol; practically insoluble in ether and other organic solvents
• Stability: Stable under normal temperature and dry conditions. Resistant to light and heat within common storage range. Decomposes under strong high temperature, strong acid or strong alkali environment.
