Methylmagnesium Chloride

Methylmagnesiumchloride

Molecular formula: CH?ClMg

Molecular weight: 74.80

Packaging/Storage: 1. Packaged in 500ml bottles, 30L steel cylinders, or 300/500L storage tanks. 2. During use, this product should be isolated from air and moisture to the greatest extent possible, and it is best to use it once immediately after opening. If color difference or micro-precipitation is found in the product, it will not affect the product performance. 3. Store at room temperature.

Basic Information

Appearance: Gray or gray-brown liquid

Density: 1.013g/ml (25℃)

Boiling point: 66℃, 80℃ (refers to the solvent, not the solute)

Flash point: -18℃, -11℃

Concentration: 1.5M, 2.0M, 2.5M, 3.0M (solutions in tetrahydrofuran or 2-methyltetrahydrofuran)

Properties

Reacts violently with water: Extremely sensitive to air and moisture, it will undergo a violent reaction when in contact with water, releasing highly flammable methane gas.

Flammable: Its solution is a flammable liquid. In humid air, due to the violent and exothermic reaction, highly flammable methane gas will be released.

Stability: It should be operated and stored under the protection of anhydrous and oxygen-free inert gases such as nitrogen or argon. Avoid contact with oxidants, acids, alcohols, etc. at room temperature.

Applications

1. Pharmaceutical synthesis: Widely used in drug synthesis. For example, in the industrial production of quinolone antibiotics, it is used as a key alkylating reagent to construct the molecular skeleton of drugs. It can also react with complex molecules such as Garner's aldehydes to synthesize biologically active compounds.

2. Catalytic materials: Can be used to prepare supported non-metallocene catalysts. This catalyst exhibits excellent stereoselectivity in olefin polymerization reactions, which is an important application direction in the field of polymer material synthesis.

3. General methylating reagent: As a synthetic reagent that can provide methyl anions (CH??), it is used to introduce methyl groups into target molecules to synthesize a variety of fine chemicals such as alcohols and ketones.
