sulfonamide: [ sul-fon´ah-mīd ] 1. a compound containing the -SO 2 NH 2 group. 2. any of a group of structurally related antibiotics that competitively inhibit folic acid synthesis in microorganisms and formerly were bacteriostatic against a wide variety of gram-positive and gram-negative bacteria and some protozoa. Because many microbes are. Preparation of Aniline via Reduction of Nitrobenzene A wide range of nitrobenzene derivatives can be easily made via regioselective nitration of substituted benzenes. Reduction of the nitrobenzene derivatives using tin/hydrochloric acid provides a convenient and high yielding route to a wide variety of aromatic amines. The simplest case is the synthesis of aniline from nitrobenzene. 2. SULPHONATION AND SULPHATION Sulphonation involves the introduction of sulphonic acid group or corresponding salt like sulphonyl halide into a organic compound while sulphationinvolves introduction of -OSO 2 OH or -SO Various sulphonating agents are sulphur trioxide and compounds, sulphurdixide, sulphoalkylating agents. Some of the sulphaming agents are sulphamic acid.

Because of the electronegative nitrogen in the pyridine ring, the molecule is relatively electron deficient. It therefore enters less readily electrophilic aromatic substitution reactions, which are characteristic of benzene can se. Typical conditions involve heating the aromatic compound with sulfuric acid: C 6 H 6 + H 2 SO 4 → C 6 H 5 SO 3 H + H 2 O.
Sulfur trioxide or its protonated derivative is the actual electrophile in this electrophilic aromatic substitution. To drive the equilibrium, dehydrating agents such as thionyl chloride can be added.

Synthesis and Identification of some New Sulphadiazine Derivatives Mustafa K. Naeem* and Ezzat H. Zimam Department of Chemistry, Faculty of Science, University of Kufa, IRAQ Email: [email protected], [email protected] Accepted on 16th July _____ ABSTRACT.
Sodium fluoride is an ionic compound, in which there is an ionic bond between oppositely charged ions. During the formation of "NaF", the sodium atom loses its single valence electron, forming a sodium ion with a 1^+ charge.
The fluorine atom gains the electron from the sodium atom, forming a fluoride ion with a charge of 1^(-)". The electrostatic attraction between the oppositely charged ions. Some pyridazine derivatives carrying urea, thiourea, and sulfonamide groups were synthesized and evaluated for their antimicrobial activity against gram-positive and gram-negative bacteria, and fungi by using broth microdilution.
The structures of these new compounds were conﬁrmed by 1 H-NMR, mass spectrum, and elemental analysis. This book is about Sulph(on)ation Technology in its technical entirety, aiming at superiority in final product quality, raw material utilisation, sustained plant reliability and safety, minimisation of liquid effluent and gaseous emissions; it is about the total quality of the by: Get Other Fluorous Compounds at Spectrum Chemical.

The class includes several groups of drugs used in the treatment of bacterial infections, diabetes mellitus, edema, hypertension, and gout.
The bacteriostatic sulfonamide drugs, often called sulfa drugs. Sulfonamides: The sulfa-related group of antibiotics, which are used to treat bacterial infection and some fungal infections. Examples of sulfonamides includes sulfadiazine, sulfamethizole (brand name: Thiosulfil Forte), sulfamethoxazole (), sulfasalazine (Azulfidine), sulfisoxazole (Gantrisin), and various high-strength combinations of three sulfonamides.
Derivatives are easily synthesized by mixing the Sulfo-NHS with a carboxyl-containing molecule and a dehydrating agent such as the carbodiimide EDC (EDAC). The method is the basis for generating many types of protein labeling reagents, including amine-reactive fluorescent dyes, biotin affinity tags and pegylation compounds.

Mechanism of sulphonation: Stage 2: This second step is different from all the other benzene electrophilic substitution reactions you might have already looked at on this site. This time there isn't a separate negative ion to remove the hydrogen atom from the ring. Instead it is removed by a lone pair on the negative oxygen atom.
