  <name>7,11-Dioxolanost-8-en-3-yl acetate</name>
  <description>7,11-Dioxolanost-8-en-3-yl acetate belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. 7,11-Dioxolanost-8-en-3-yl acetate is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa).</description>
