What is Dodine?

Plain description, key identifiers and synonyms

1-dodecylguanidine acetate is an acetate salt resulting from the reaction of equimolar amounts of 1-dodecylguanidine and acetic acid. It is used as a fungicide to control black spot and foliar diseases on apples, pears, peaches, nectarines and strawberries. It has a role as an antibacterial agent and an antifungal agrochemical. It is an acetate salt and an aliphatic nitrogen antifungal agent. It contains a 1-dodecylguanidine(1+).
