Sulfonamide functional group Hydrochlorothiazide is a sulfonamide and a thiazide. Furosemide is a sulfonamide, but not a thiazide. Sulfamethoxazole is an antibacterial sulfonamide. Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The structure of the sulfonamide group. In organic chemistry, the sulfonamide functional group (also spelled sulphonamide) is an organosulfur group with the structure R−S(=O) 2 −NR 2. It consists of a sulfonyl group (O=S=O) connected to an amine group (−NH 2). Relatively speaking this group is unreactive.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
Radium sulfate is the most insoluble sulfate known. The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to ...
Sulfacetamide is a sulfonamide antibiotic. [1] Sulfonamides are synthetic bacteriostatic antibiotics, that are active against gram-positive and gram-negative bacteria. It blocks the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. It is a competitive inhibitor of bacterial para-aminobenzoic acid (PABA).
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.
Being extremely soluble in water, ammonium sulfate can "salt out" (precipitate) proteins from aqueous solutions. [ 3 ] [ 4 ] Precipitation by ammonium sulfate is a result of a reduction in solubility rather than protein denaturation , thus the precipitated protein can be resolubilized through the use of standard buffers .
