Class Information
Number: 514/266.1
Name: Drug, bio-affecting and body treating compositions > Designated organic active ingredient containing (doai) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., o,s,se or te) or nitrogen as the only ring hetero atoms doai > Hetero ring is six-membered consisting of two nitrogens and four carbon atoms (e.g., pyridazines, etc.) > 1,3-diazines (e.g., pyrimidines, etc.) > Polycyclo ring system having 1,3-diazine as one of the cyclos > Bicyclo ring system having the 1,3-diazine as one of the cyclos > Quinazoline (including hydrogenated)(i.e., the second cyclo in the bicyclo ring system is an ortho-fused six-membered carbocycle)
