HYDROQUINIDINE, also known as Dihydroquinidine, is a white crystalline solid at room temperature and pressure. It is insoluble in water and has a certain alkalinity. HYDROQUINIDINE is a hydrogenated derivative of quinidine and has certain biological activity. It can be used as an intermediate in or...
Figure 1: Image of Methyl-5-norbornene-2,3-dicarboxylic anhydride Properties Methyl-5-norbornene-2,3-dicarboxylic anhydride contains a norbornene unit and an acid anhydride structure, which gives it extremely high chemical reactivity. It reacts vigorously with water or other protonic organic solvents...
