Laboratory synthesized sulfanilamide. Sulfanilamide is a yellowish-white or white crystal or fine powder. It has a density of 1.08 g/cm 3 and a melting point of 164.5-166.5 °C. The pH of a 0.5% aqueous solution of Sulfanilamide is 5.8 to 6.1. It has a λ max of 255 and 312 nm. [5]
Many important drugs contain the sulfonamide group. [1] A sulfonamide (compound) is a chemical compound that contains this group. The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2.
Chemical structure of a generic acylsulfonamide. Acylsulfonamide is a functional group in organic chemistry that is sometimes used in medicinal chemistry. [1] It consists of a sulfonamide group (SO 2 NH) linked to an acyl group (RCO), forming the structure R 1-CO-NH-SO 2-R 2.
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.
Sulfenamides have been characterized by X-ray crystallography.The S-N bond in sulfenamides is a chiral axis that leads to formation of diastereomeric compounds. The existence of these distinct stereoisomers is due to the formation of a partial double bond between either sulfur or nitrogen's lone pair and the other atom's antibonding orbitals. [1]
General chemical structure of a sulfanilide. In organic chemistry, a sulfonanilide group is a functional group found in certain organosulfur compounds.It possesses the chemical structure R−S(=O) 2 −N(−C 6 H 5)−R', and consists of a sulfonamide group (R−S(=O) 2 −NR'R") where one of the two nitrogen substituents (R' or R") is a phenyl group (C 6 H 5).
Sulfanilic acid (4-aminobenzenesulfonic acid) is an organic compound with the formula H 3 NC 6 H 4 SO 3. It is an off-white solid. It is a zwitterion, which explains its high melting point. It is a common building block in organic chemistry. [4]
3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
