Methylmagnesium chloride
CAS No.: 676-58-4
Molecular Formula: CH3ClMg
Molecular Weight: 74.79
Physical and Chemical Properties
- Appearance: Colorless to pale yellow clear liquid (typically supplied as THF solution)
- Density: 1.013–1.04 g/mL at 25 °C
- Boiling Point: 66 °C (THF solvent)
- Flash Point: -17 °C
- Solubility: Reacts violently with water; miscible with ether, THF, and 2-MeTHF
- Stability: Highly moisture-sensitive; stable under inert atmosphere (N?/Ar); decomposes above 80 °C
Application
- Grignard reagent: Core alkylating agent for C–C bond formation in organic synthesis
- Pharmaceutical synthesis: Key intermediate for quinolone antibiotics, steroids, and vitamin derivatives
- Fine chemical manufacturing: Used in production of fragrances, agrochemicals, and specialty alcohols
- Polymer chemistry: Catalyst for anionic polymerization and as a crosslinking agent
Storage Condition
Store in tightly sealed, moisture-proof containers under inert gas (N?/Ar). Keep at 40 °C or below, away from heat, direct sunlight, and oxidants. Avoid contact with water, alcohols, and protic solvents.
