Dihydralazine sulfate, scientifically known by its CAS number 7327-87-9, is a compound that holds significant importance in the pharmaceutical sector due to its vasodilatory and antihypertensive properties. Chemically, it is a derivative of phthalazine and belongs to the hydrazinophthalazine class. This classification highlights its structural relationship to other well-known vasodilators, offering a unique profile of efficacy in managing cardiovascular conditions, primarily hypertension.

The physical characteristics of dihydralazine sulfate typically describe it as an off-white to pale yellow powder, with a melting point generally above 235°C with decomposition. Its solubility in DMSO makes it amenable to various laboratory and formulation processes, a key consideration for R&D scientists and formulators looking to buy this chemical. The molecular formula, C8H12N6O4S, and a molecular weight of approximately 288.28 g/mol, are critical data points for chemists and pharmacologists assessing its suitability for specific applications.

The primary mechanism of action for dihydralazine sulfate involves the direct relaxation of vascular smooth muscle. It functions by reducing the influx of calcium ions into these cells, which are necessary for muscle contraction. This vasodilation leads to a decrease in peripheral vascular resistance, thereby lowering blood pressure. This pharmacological action makes it a valuable component in the synthesis of drugs used to treat hypertension. Researchers and product formulators seeking to purchase this compound can rely on reputable suppliers for consistent chemical profiles and purity.

Beyond its role in hypertension, dihydralazine sulfate may find applications in specific therapeutic areas where vasodilation is beneficial. Its precise application and dosage are determined by extensive clinical research and regulatory approvals. For those in product development or manufacturing, sourcing high-quality dihydralazine sulfate from established chemical suppliers is essential to ensure the safety and efficacy of the final pharmaceutical products. Understanding the chemical profile and application scope is the first step for any professional looking to incorporate this compound into their research or production pipelines.
