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.
The cyanide compound sodium nitroprusside is used mainly in clinical chemistry to measure urine ketone bodies mainly as a follow-up to diabetic patients. On occasion, it is used in emergency medical situations to produce a rapid decrease in blood pressure in humans; it is also used as a vasodilator in vascular research.
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
Roussin's black salt is a chemical compound with the formula KFe 4 S 3 (NO) 7. [1] It consists of the potassium salt of the [Fe 4 S 3 (NO) 7] − anion, metal nitrosyl compound. First described by Zacharie Roussin in 1858, [2] it is one of the first synthetic iron-sulfur clusters along with the red salt also bearing his name.
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 ...
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 ...
