白色结晶体粉末,有轻微氯气臭味;味苦。置空气中缓慢分解,渐渐失去氧而变成黄色。有效期为23%~26%,熔点167~170℃(分解)。易溶于水,溶于乙醇、甘油,不溶于氯仿、乙醚和苯。在水和乙醇中缓缓分解,在酸性介质中剧烈分解,放出氧气。其水溶液缓冲至pH值为9时较稳定。无水物在175~180℃时爆炸。在90~100℃干燥时不分解。
由对甲苯磺酰氯经胺化生成对甲苯磺酰胺,再用次氯酸钠溶液氯化来制得。
用作工业水处理杀菌灭藻剂,可与其杀菌剂配合使用。配成0. 0004%水溶液进行消毒处理,1%~2%溶液可采用直接投药。此外,在印染工业用作漂白剂,主要用以植物纤维及人造丝等织物的漂白,还可用作棉布的氧化退浆剂。
对黏膜刺激作用小,吸入使中枢神经机能受到抑制,出现气喘症状。贮运时应避免光照,置于阴凉处保存,运输时防雨、防潮、防晒,不可与有机物接触。

体外研究 | 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. |
体内研究 | 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. |
