该白色结晶体粉末具有轻微的氯气臭味,并且有苦味,会缓慢地分解在空气中,逐渐失去氧和变成黄色。它的有效期为23%~26%,熔点为167~170℃(分解)。该物质可以溶于水、乙醇和甘油,但不溶于氯仿、乙醚和苯。在水和乙醇中缓慢地分解,在酸性介质中剧烈地分解,产生氧气。它的水溶液在pH值为9时较稳定。当无水物体温度达175~180℃时会爆炸,当90~100℃干燥时不会分解。
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。
杀菌灭藻剂可用于工业水处理,可与其配成0.0004%的水溶液进行消毒处理。可采用1%~2%的溶液直接投药。此外,杀菌灭藻剂也可用作漂白剂,主要用于植物纤维及人造丝等织物的漂白,并可用于棉布的氧化退浆剂。
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。吸入使中枢神经机能受到抑制,出现气喘症状。对黏膜刺激作用小。

| 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. |
