    en.wikipedia.org/wiki/Sulfanilamide

    Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. [ 1 ] Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to ...

    This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.

  4. Sulfamide - Wikipedia

    en.wikipedia.org/wiki/Sulfamide

    Sulfamide (IUPAC name: sulfuric diamide) is a compound with the chemical formula SO 2 (NH 2) 2 and structure H 2 N−S(=O) 2 −NH 2. Sulfamide is produced by the reaction of sulfuryl chloride with ammonia. Sulfamide was first prepared in 1838 by the French chemist Henri Victor Regnault. [2]

  5. Sulfinamide - Wikipedia

    en.wikipedia.org/wiki/Sulfinamide

    In organosulfur chemistry, sulfinamide is a functional group with the structure R−S(O)−NR 2 (where R = alkyl or aryl). [1] This functionality is composed of a sulfur - carbon ( S−C ) single bond , a sulfur- nitrogen ( S−N ) single bond , and a sulfur-oxygen (S-O) bond (see Sulfoxide for the nature of this bond) [ 2 ] .

  6. Sulfonamide - Wikipedia

    en.wikipedia.org/wiki/Sulfonamide

    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.

    en.wikipedia.org/wiki/Prontosil

    Prontosil is an antibacterial drug of the sulfonamide group. It has a relatively broad effect against gram-positive cocci but not against enterobacteria.One of the earliest antimicrobial drugs, it was widely used in the mid-20th century but is little used today because better options now exist.
