1. Basic Information
Name: Methylamine hydrochloride
Alias: Methanaminium chloride
CAS No.: 593-51-1
Molecular Formula: C1H6N1Cl1
Molecular Weight: 67.52
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Slight methylamine irritating odor
- Solubility: Highly soluble in water, soluble in methanol and ethanol; slightly soluble in isopropanol; insoluble in ether, acetone, benzene
- Melting Point: 232–234 °C
- Hygroscopicity: Strongly hygroscopic, easy to absorb moisture and deliquesce in humid air
- Aqueous solution: Weakly acidic transparent liquid
Chemical Properties
- Molecular Structure: Ionic salt composed of methylammonium cation and chloride anion
- Alkali reaction: Reacts with sodium hydroxide, potassium hydroxide and other strong alkalis under heating to release volatile methylamine gas with strong pungent smell
- Thermal stability: Stable at room temperature; decomposes above melting point to produce methylamine and hydrogen chloride gas
- Salt compatibility: Stable with neutral inorganic salts; precipitates with silver ions to form silver chloride white precipitate
- Photostability: Stable under indoor light, no discoloration
- Compatibility: Compatible with polar organic solvents and weak acid systems; incompatible with strong alkalis, silver salts, oxidants

Safety Warning
Strong irritant solid. Dust severely stimulates eyes, skin and respiratory tract; contact with strong alkali releases highly irritating methylamine gas. Wear dust mask, acid-resistant gloves and full-face goggles during operation, operate in ventilated environment. Strictly avoid mixing with alkaline materials. Waste liquid needs neutralization treatment before discharge; residues belong to nitrogen-containing organic hazardous waste requiring professional disposal.
