Isosorbide dinitrate is in the nitrate family of medications and works by dilating blood vessels. [1] Isosorbide dinitrate was first written about in 1939. [3] It is on the World Health Organization's List of Essential Medicines. [4] Isosorbide dinitrate is available as a generic medication. [1] [5] A long-acting form exists. [1]
The first long-acting (depot) injections were antipsychotics fluphenazine and haloperidol. [2] The concept of a depot injection arose before 1950, and originally was used to describe antibiotic injections that lasted longer to allow for less frequent administration. [4]
Praseodymium(III) nitrate is any inorganic compound with the chemical formula Pr(NO 3) 3 ·xH 2 O. These salts are used in the extraction and purification of praseodymium from its ores. [2] The hexahydrate has been characterized by X-ray crystallography. [3] Praseodymium nitrate can be prepared by treating praseodymium oxide with nitric acid:
The compound is a salt with separated hydroxyammonium and nitrate ions. [2] Hydroxylammonium nitrate is unstable because it contains both a reducing agent (hydroxylammonium cation) and an oxidizer , [3] the situation being analogous to ammonium nitrate. It is usually handled as an aqueous solution with small amount of nitric acid as a stabilizer.
Solutions of lead nitrate can be used to form co-ordination complexes. Lead(II) is a hard acceptor ; it forms stronger complexes with nitrogen and oxygen electron-donating ligands. For example, combining lead nitrate and pentaethylene glycol (EO 5 ) in a solution of acetonitrile and methanol followed by slow evaporation produced the compound ...
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
Rhodium(III) nitrate is a inorganic compound, a salt of rhodium and nitric acid with the formula Rh(NO 3) 3. This anhydrous complex has been the subject of theoretical analysis but has not been isolated. [ 4 ]
Lanthanum(III) nitrate is any inorganic compound with the chemical formula La(NO 3) 3 ·xH 2 O. It is used in the extraction and purification of lanthanum from its ores. It is used in the extraction and purification of lanthanum from its ores.
