Molecular Formula: C5H9BrMg

Molecular Weight: 173.34

Basic Information

Appearance: Gray to taupe liquid

Density: 0.996g/ml (25°C)

Boiling Point: 66°C (refers to the solvent, not the solute)

Flash Point: -36°C

Concentration: 1.0M, 2.0M (tetrahydrofuran solution)

Properties

Violent reaction with water: Extremely sensitive to air and moisture, will undergo violent reaction when exposed to water, releasing flammable cyclopentane.

Flammable: In humid air, due to the violent exothermic reaction, flammable cyclopentane will be released.

Stability: Operations and storage should be carried out 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. General Grignard reagent: Mainly used in the synthesis of fine chemicals such as pharmaceuticals, pesticides and spices, for introducing cyclopentyl structures.

2. Special cyclopentylation reagent for organic synthesis.

3. Construction of compounds containing five-membered carbocyclic skeletons.

Packaging/Storage

1. 500ml glass bottles; 200L iron drums and steel cylinders.

2. During the opening process of this product, isolate air and moisture to the greatest extent, and it is best to use it immediately once opened. If color difference or micro-precipitation is found in the product, it will not affect the product performance.

3. Store at room temperature.
