Dipropyltin dichloride is an organotin compound with the chemical formula (CH3CH2CH2)2SnCl2.

This chemical belongs to a subclass of organotin compounds called diorganotin dihalides (R2SnX2, where R is organyl and X is a halogen).

It is suspected this chemical is a human mutagen and teratogen, and toxic to the reproductive system.

Dipropyltin dichloride may react violently with strong oxidizing agents.

Upon catching fire, irritating and toxic fumes, gases and smokes are released, like carbon monoxide (CO), carbon dioxide (CO2), tin(II) oxide (SnO), tin(IV) oxide (SnO2) and hydrogen chloride (HCl).
