Uses

Ophthazin is an antihypertensive agent of the hydrazine class used during pregnancies in dialysis patients with familial mediterranean fever and cystinosis under hemodialysis.

Definition

ChEBI: Dihydralazine is a member of phthalazines.

Manufacturing Process

115 parts of hydrazine hydrate in 80 parts 50% acetic acid were added to 128 parts of phthalic acid dinitrile in 250 parts dioxane. The mixture was heated at the temperature 95°C for 3 hours with stirring. After 20 minutes the crystallization and discharging of NH3 began. The orange needles were filtered off after cooling. The product was washed with dioxane and ethanol and recrystallized from 3000 parts of water to yield 110 parts colorless needles of 1,4-dihydrazino-phthalazine; MP: 191°-193°C (decomp.). The crystals were getting a little orange color by standing because of a reaction with an air oxygen.

Therapeutic Function
