Properties

This product is mainly used as an intermediate in the synthesis of medicine or pesticide, and can be used in the synthesis of doxazosin. Doxazosin is a α 1 selectivity α A blocker that inhibits norepinephrine from interacting with the membrane of vascular smooth muscle cells α- 1 receptor binding. The main effect of this inhibition is to relax the tension of vascular smooth muscle (vasodilation), which reduces peripheral vascular resistance and leads to lower blood pressure. * it is used clinically to treat hypertension and urinary retention associated with benign prostatic hyperplasia.
