2,6- dimethyl-4- tridecylmorpholin belongs to the group of the alkylated morpholine. It acts as an inhibitor of sterol biosynthesis by intervening in the ergosterol synthesis. Used was 2,6- dimethyl-4- tridecylmorpholin as a main component in admixture with its isomer as a fungicide active ingredient under the name of tridemorph.

Tridemorph

Tridemorph is a fungicide agent that was developed in the 1960s by BASF and 1969 newly registered. It was sold under the trade name Calixin and used to contain the fungus Erysiphe graminis (powdery mildew ) in cereals, Mycosphaerella species in bananas and Caticum solmonicolor in tea. Furthermore, it is used as a wood preservative (in conjunction with alkylammonium ).

Chemically it is a mixture of isomers of different Tridemorph morpholine derivatives with different length and branching of the alkyl chains and not defined stereochemical configuration at Morpholingerüst. Main component with 60 to 70% is 2,6- dimethyl-4- tridecylmorpholin. The chain length and the absolute configuration play only a minor role in terms of effectiveness as a fungicide.

In Germany, Austria and Switzerland it is no longer authorized as pesticides.

It is believed that Tridemorph can cause damage to human embryos when the mother of the child comes into contact with Tridemorph.
