Overview
Benzthiazide is a thiazide diuretic belonging to the benzothiadiazine class. It is primarily used in the treatment of hypertension and edema by promoting the excretion of sodium and water through the kidneys. The compound was developed as part of the sulfonamide diuretics, which revolutionized the management of cardiovascular conditions in the mid-20th century. Benzthiazide is synthesized through a series of chemical reactions involving sulfonamide and benzothiadiazine precursors. Its pharmacological action is attributed to the inhibition of the sodium-chloride symporter in the distal convoluted tubule of the nephron, leading to increased urine output and reduced blood volume.
Physical and Chemical Properties
Benzthiazide is a white to off-white crystalline powder with a molecular weight of 431.93 g/mol. Its melting point ranges between 230-235°C, and it is slightly soluble in water but more soluble in alkaline solutions. The compound is stable under standard storage conditions but should be protected from moisture and light to prevent degradation. The molecular structure of benzthiazide includes a sulfonamide group, which is critical for its diuretic activity. The presence of a benzylthio group enhances its lipid solubility, facilitating absorption in the gastrointestinal tract. These properties make benzthiazide an effective oral medication for managing fluid retention and high blood pressure.
Main Applications
Benzthiazide is primarily used in the treatment of hypertension (high blood pressure) and edema associated with congestive heart failure, liver cirrhosis, and renal disorders. It is often prescribed as part of a combination therapy with other antihypertensive agents to enhance efficacy and reduce side effects. In addition to its medical applications, benzthiazide is sometimes used in research settings to study renal physiology and the mechanisms of diuretic action. Its ability to modulate electrolyte balance makes it a valuable tool for investigating kidney function and fluid homeostasis.
Safety and Storage
Benzthiazide should be handled with care to avoid inhalation or skin contact. Personal protective equipment (PPE), such as gloves and safety goggles, is recommended when working with the compound. In case of accidental exposure, rinse affected areas with plenty of water and seek medical attention if necessary. Proper storage conditions include a cool, dry place away from direct sunlight and moisture. The compound should be kept in tightly sealed containers to prevent contamination and degradation. Disposal should comply with local regulations for pharmaceutical waste.
B2B Procurement Guide
When procuring benzthiazide, B2B buyers should verify the CAS number (91-33-8) and request a Certificate of Analysis (COA) to confirm purity and quality. Reputable suppliers should also provide a Material Safety Data Sheet (MSDS) detailing handling, storage, and safety precautions. Prices typically range from $50 to $100 per kilogram, depending on the quantity and purity required. Bulk purchases may qualify for discounts. Buyers should also consider logistical factors, such as shipping conditions and lead times, to ensure timely delivery and product integrity.
