The chemical reactions of sodium nitroprusside are mainly associated with the NO ligand. [51] For example, addition of S 2− ion to [Fe(CN) 5 (NO)] 2− produces the violet colour [Fe(CN) 5 (NOS)] 4− ion, which is the basis for a sensitive test for S 2− ions. An analogous reaction also exists with OH − ions, giving [Fe(CN) 5 (NO 2)] 4− ...
Sodium nitroprusside, a medicinally significant metal nitrosyl-pentacyanoferrate (Fe-III) compound, used to treat hypertension. [1] Metal nitrosyl complexes are complexes that contain nitric oxide, NO, bonded to a transition metal. [2] Many kinds of nitrosyl complexes are known, which vary both in structure and coligand.
A solution of 2% sodium carbonate in water (solution B) [4] Separate storage of the aldehyde and base are necessary to prevent aldol polymerisation of the aldehyde. When exposed to an amine, reaction with acetaldehyde produces the enamine, which subsequently reacts with sodium nitroprusside to the imine.
Nitrates undergo chemical reduction, likely mediated by enzymes. Molsidomine and nitroprusside already contain nitrogen in the right oxidation state (+2) and liberate NO without the aid of enzymes. [3] NO stimulates the soluble form of the enzyme guanylate cyclase in the smooth muscle cells of blood vessels.
Clevidipine also contains glycerin (22.5 mg/mL), purified egg yolk phospholipids (12 mg/mL), and sodium hydroxide to adjust pH. Clevidipine has a pH of 6.0–8.0 Clevidipine has a pH of 6.0–8.0 In the perioperative patient population Clevidipine produces a 4–5% reduction in systolic blood pressure within 2–4 minutes after starting a 1–2 ...

Mössbauer spectrum of sodium nitroprusside, exhibiting quadruple splitting. Quadrupole splitting is an example of a hyperfine interaction found in gamma-ray spectroscopy, in the circumstance where nuclei with a non-radially-symmetric shape (that is, with a spin quantum number greater than 1/2) are found immersed in an external electric field gradient.
After neutralization of this intermediate with sodium carbonate, red crystals of sodium nitroprusside can be selectively crystallized. [8] Upon treatment with chlorine gas, potassium hexacyanidoferrate(II) converts to potassium hexacyanidoferrate(III): 2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl
