Sulfamethoxazole is a bacteriostatic sulfonamide antibiotic that interferes with folic acid synthesis in susceptible bacteria. The treatment of cotton fabrics with 4-aminobenzenesulfonic acid-chloro-triazine adduct increased the anionic sites on the fabric surface and facilitated the exhaustion of QACs Son et al 2006.

4 aminobenzenesulfonic acid. 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. Sulfanilic acid can be produced by sulfonation of aniline. As the compound readily forms diazo compounds it is used to make dyes.
Coupling between salicylic acid and 4-aminobenzenesulfonic acid Procedure 1. In test tube A add approximately 05 mL of conc. HCl and place in an ice water bath.
In test tube B place 049 g 28 mmol of sulfanilic acid 013 g of sodium carbonate Na 2 CO 3 and 5 mL of water and place in a hot water bath until a clear solution is obtained. In test tube C prepare a. 4-aminobenzene sulfonic acid appears as white powder with faint purple tinge.
Becomes anhydrous at around 212F. Low toxicity used medicinally. 4-aminobenzenesulfonic acid is an.
The cards are data sheets intended to provide essential safety and health information on chemicals in a clear and concise way.

An organic dyeused as an acidbase indicator. Itchanges from red below pH 31 toyellow above pH 44 at 25C and isused for titrations involving weakbases. 製造方法 4-Aminobenzenesulfonic acid diazo and NN-dimethylaniline coupling.
The treatment of cotton fabrics with 4-aminobenzenesulfonic acid-chloro-triazine adduct increased the anionic sites on the fabric surface and facilitated the exhaustion of QACs Son et al 2006. In the study the exhaustion was affected by pH concentration temperature and exhaustion time. For polyester fibres which contain carboxylic or sulfonate groups QAC can be directly exhausted.
Sulfamethoxazole is a bacteriostatic sulfonamide antibiotic that interferes with folic acid synthesis in susceptible bacteria. It is generally given in combination with trimethoprim which inhibits a sequential step in bacterial folic acid synthesis - these agents work synergistically to block two consecutive steps in the biosynthesis of nucleic acids and proteins which are necessary for.
