3-Chloropropyne (Propargyl Chloride) About

Propargyl Chloride

CAS No.: 624-65-7

Appearance and properties: Light yellow liquid.

Assay: 65% or 85%
Flammability: Highly flammable.
Explosive: 3-chloropropyne is explosive
Solubility: Insoluble in water, but miscible with benzene, toluene, carbon tetrachloride, as well as ethanol, ether and ethyl acetate.
Refractive index: 1.4320

Application:
It is used as an intermediate in organic synthesis. It is used for manufacturing the drug Eugenin, soil fumigants, etc. It is also a modifier for engineering plastics. Its trisodium salt is an excellent heat stabilizer for polyvinyl chloride, and its esters are also important additives for polymers.
2. Organic synthesis intermediates, such as those used in the production of the medicine "Youjiangning", can also be used in the production of soil fumigants.
3. Propargyl chloride is a three-carbon alkylating reagent and also an equivalent of the acetone carboene ion, a ring-increasing reagent, and when converted to a metal-organic reagent, it becomes a nucleophile for alkyne or propylene groups.

Key Applications in Industry

3-Chloropropyne is widely used in pharmaceutical, agricultural, and polymer industries. It acts as a precursor to medicines like Eugenin, soil fumigants, and specific electroplating agents. Its chemical features also make it ideal for enhancing properties in plastics and offering robust corrosion protection for metals.


Chemical and Physical Properties

This compound appears as a yellowish liquid, with a density of 1.0297 g/m3 and is supplied at high purity levels. Its presence in trisodium salt form brings excellent heat stabilization to polymers, notably polyvinyl chloride. The product should be stored at room temperature and maintains efficacy for up to two years.
