In vitro study | Gram-positive growth is reduced by 95% to 100% after tosylchloramide treatment, regardless of dose, with or without serum. E coli (gram-negative; with/without serum) is reduced 94% to 100% at antiseptic concentrations of 300 and 400 ppm. At 200 ppm, E coli growth is fully inhibited without serum present and by 50% with serum. At 100 and 200 ppm, cell viability remains greater than 90% under all experimental conditions. A 300-ppm, 3-minute exposure to tosylchloramide results in cell viability of up to 70%, with longer exposures producing lower viabilities. Serum does not affect cell viability in any condition. |
In vivo study | A dose-dependently significant DNA damage in the rat tissues and inflammation is histopathologically noted around the terminal airways of the lung in both male and female rats. The 24-h exposure to 50 mg/L of chloramine-T is toxic for crayfish and leads to substantial loss of energy that became apparent during subsequently conducted physical stress. Tosylchloramide may potentiate the toxicity of many xenobiotics via metabolic activation and/or accumulation of reactive metabolites. The activities of CYP2E1, CYP1A1/2 CYP2B1/2, CYP3A4 and CYP4A1/2 enzymes significantly increase after treatment with 2.50, 5 and 10 mg/kg bw/day tosylchloramide, in a dose-dependent manner. This effect is not observed after tosylchloramide treatment at dose of 1.25 mg/kg bw/day. |

white crystalline powder, with slight chlorine odor; Bitter taste. Slow decomposition in air, gradually lose oxygen and become yellow. Valid for 23% ~ 26%, the melting point of 167~170 deg C (decomposition). Soluble in water, soluble in ethanol, glycerol, insoluble in chloroform, ether and benzene. Slowly decompose in water and ethanol, and decompose vigorously in acidic medium, releasing oxygen. When the aqueous solution is buffered to pH 9, it is more stable. The anhydrate exploded at 175-180 °c. It does not decompose when dried at 90-100 °c.
p-Toluenesulfonyl chloride was aminated to form p-toluenesulfonamide, and then chlorinated with sodium hypochlorite solution.
It is used as a bactericidal algicide for industrial water treatment, and can be used in combination with its bactericide. Prepared into 0. 0004% aqueous solution for Disinfection treatment, 1%~ 2% solution can be directly administered. In addition, it is used as a bleaching agent in the printing and dyeing industry, mainly for the bleaching of plant fibers and rayon and other fabrics, and can also be used as an oxidative Desizing agent for cotton.
The effect of mucosal stimulation is small, and the central nervous system function is inhibited by inhalation, and asthma symptoms occur. Storage and transportation should avoid light, stored in a cool place, rain-proof, moisture-proof, sunscreen, not with organic contact.
