Description

Prazosin CAS NO 19216-56-9 is a selective α-1 adrenergic receptor antagonist of the quinazoline class. This compound is of critical importance as a key active pharmaceutical ingredient (API) and a vital reference standard in pharmaceutical research and development. It is primarily required by pharmaceutical manufacturers, contract research organizations (CROs), and analytical laboratories for the production of antihypertensive medications and for use in bioanalytical studies and quality control processes.

Application

• Active Pharmaceutical Ingredient (API) in the manufacture of antihypertensive drugs.
• Pharmaceutical reference standard for analytical method development and validation.
• Key intermediate in advanced pharmaceutical synthesis and process research.
• Critical material for bioequivalence and pharmacokinetic studies in clinical research.
• Raw material for the preparation of finished dosage forms (e.g., tablets, capsules).
• Research chemical in cardiovascular and urological pharmacological studies.
