Intermediate
3-Chloropropyne CAS:624-65-7
3-Chloropropyne molecules contain a carbon-carbon triple bond and a chlorine atom, and have typical chemical properties of both. The carbon-carbon triple bond can undergo addition reactions, such as with hydrogen, halogens, and hydrogen halides; the chlorine atom has a certain degree of activity and can undergo substitution reactions, such as being replaced by hydroxyl groups, amino groups, etc. under alkaline conditions.

3-Chloropropyne is used to synthesize medicines such as Pargyline, and can also be used to make pesticide soil fumigants.
Used for synthesizing electroplating intermediates, pharmaceutical intermediates and pesticide intermediates. It is an excellent metal corrosion inhibitor and rust preventer.
Chloropropin is an intermediate of the pyrethroid praloxithrin.
It is used as an organic synthesis intermediate. It is used to manufacture the drug paroxysmal, 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.
3-Chloropropyne is highly toxic and a strong irritant to the eyes, skin, respiratory tract, and digestive tract. Inhalation or ingestion may cause serious health problems or even be life-threatening.
It is a flammable liquid, and its vapor can form an explosive mixture with air, which can cause combustion and explosion when exposed to open flames or high heat. During use and storage, safety regulations must be strictly followed, good ventilation must be maintained, contact with fire sources, oxidants, etc. must be avoided, and appropriate protective measures must be taken, such as wearing protective glasses, gloves, respirators, etc.
