(+)-Usniacin Usage And Synthesis
Contact allergensUsnic acid is a component of lichens, also used as a topical antibiotic. Allergic contact dermatitis from lichens occurs mainly occupationally in forestry and horticultural workers, and in lichen pickers.
Purification MethodsThis very weak acid is the natural form which is recrystallised from Me2CO, MeOH or *C6H6. At 25o it is soluble in H2O (<0.01%), Me2CO (0.77%), EtOAc (0.88%), MeOCH2CH2OH (0.22%) and furfural (7.32%).
