11). New molecules were obtained by the reaction of carabrone with an appropriate substituted benzenesulfonic acid hydrazide. Synthesized compounds 17, 18 showed an inhibitory effect on the germination of spores of Colletotrichum lagenarium and Botrytis cinerea in vitro conditions, reaching IC50 values...
Combustible when exposed to heat or flame; can react vigorously with oxidizing materials.Dust explosion possible if in powder or granular form, mixed with air.All three isomers have similar properties and may react vigorously with oxidizing materials. Their reaction with nitric acid (nitration) will...
