  "term": "Azines",
  "field": "Chemistry",
  "definition": "Compounds of the type R2C=N-N=CR2, formed when hydrazine condenses with two molecules of an aldehyde or ketone. They differ from hydrazones R2C=N-NH2, which keep an NH2 group and are intermediates on the way to azines, and E/Z isomerism about the two C=N double bonds is possible. The ending -azine in Hantzsch-Widman heterocycle names, such as 1,3-oxazine, is an unrelated usage.",
