Structure of sodium nitroprusside in the solid state, obtained by neutron diffraction Space filling model of sodium nitroprusside Nitroprusside is an inorganic compound with the chemical formula Na 2 [Fe(CN) 5 NO], usually encountered as the dihydrate , Na 2 [Fe(CN) 5 NO]·2H 2 O. [ 47 ] This red-colored sodium salt dissolves in water or ...
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.
Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter. [13] Iodine is an essential component of thyroxine. Since thiocyanates will decrease iodide transport into the thyroid follicular cell, they will decrease the amount of thyroxine produced by the thyroid gland.
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
The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
Glyceryl trinitrate (nitroglycerine) Molsidomine Sodium nitroprusside. The nitrates are used for the treatment and prevention of angina and acute myocardial infarction, while molsidomine acts too slowly to be useful for the treatment of acute angina. [2]
The French chemist Z. Roussin [5] first prepared this salt while investigating reactions between nitroprusside ion ([Fe(CN) 5 NO] 2−) and sulfur. [6] The salt can be prepared by the reaction of sulfide salts with iron nitrosyl halides: [7] Fe 2 I 2 (NO) 4 + 2Li 2 S → Li 2 Fe 2 S 2 (NO) 4 + 2LiI
S-Nitroso-N-acetylpenicillamine (SNAP) is the organosulfur compound with the formula ON S C(CH 3) 2 C H(N H Ac)CO 2 H.It is a green solid. [2]SNAP is an S-nitrosothiol and is used as a model for the general class of S-nitrosothiols which have received much attention in biochemistry because nitric oxide and some organic nitroso derivatives serve as signaling molecules in living systems ...
