Sodium nitroprusside dihydrate

Description:
Sodium nitroprusside dihydrate is an inorganic compound with the formula Na2[Fe(CN)5NO]·2H2O. It appears as a deep red or purple crystalline solid and is highly soluble in water. This compound is primarily used in medical settings as a potent vasodilator for the rapid reduction of blood pressure in hypertensive emergencies. Its mechanism of action involves the release of nitric oxide, which relaxes vascular smooth muscle. Sodium nitroprusside dihydrate is sensitive to light and should be protected from exposure to prevent degradation. In terms of stability, it can decompose to release toxic cyanide ions, necessitating careful handling and monitoring during use. The compound is also utilized in various laboratory applications, including as a reagent in analytical chemistry for detecting certain metal ions. Due to its potent effects and potential toxicity, sodium nitroprusside dihydrate must be administered under strict medical supervision.
