Products Description
Introduction and application of CAS:1445-69-8|Phthalhydrazide
Used as an intermediate for pharmaceutical dihydralazophthalazine. The production method is obtained by reacting phthalic anhydride and hydrazine hydrate. Put ethanol, hydrazine hydrate, and phthalic anhydride into the reaction pot in sequence, stir, and heat up to reflux for 8 hours. Evaporate the ethanol until the reactant becomes a paste. Cool to 40°C, add appropriate amount of water, filter, wash with water to pH 6.5, and dry to obtain diketophthalazine.
