It has the chemical formula C3H7Cl and is prepared by reacting n-propyl alcohol with phosphorus trichloride in the presence of a zinc chloride catalyst.

In a rat study, the LD50 (lethal dose for 50% of the test subjects) for oral ingestion was found to be greater than 2 grams per kilogram of body weight.

In the atmosphere, it can undergo degradation through reaction with hydroxyl radicals, with an estimated half-life of about 15 days.

It can rapidly volatilize from water surfaces, and its potential for bioconcentration in aquatic organisms is considered low.

Additionally, the general population can be exposed to 1-chloropropane through inhalation of ambient air and dermal contact with vapors and products containing the compound.
