Description

Hydralazine is a potent pharmaceutical active ingredient and a direct-acting vasodilator. It is a critical compound for the development and production of antihypertensive medications, primarily used to manage high blood pressure and heart failure. This high-purity chemical is essential for pharmaceutical manufacturers, research institutions, and fine chemical synthesis requiring a reliable and consistent API source.

Application

• Pharmaceutical API: Primary active ingredient in antihypertensive and heart failure medications.
• Research & Development: Used in pharmacological studies for cardiovascular disease models and vasodilation mechanisms.
• Reference Standard: Serves as a certified reference material (CRM) for analytical method development and quality control in labs.
• Fine Chemical Synthesis: Intermediate for the synthesis of more complex pharmaceutical molecules and derivatives.
• Veterinary Medicine: Applied in the formulation of treatments for hypertension in animals.

Quality Control

Our Hydralazine is manufactured under strict quality management systems. It undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with each batch, detailing purity, identity, and impurity profiles. We can supply material compliant with various pharmacopeial monographs (e.g., USP, EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and purity.
