产品简介:一种稍带氯气味。在干燥空气中逐渐失去水分,露置空气中渐渐分解而析出氯。容量分析中用作碘及次氯酸盐标准溶液的代用品,检定溴酸盐和卤素,测定碘化物、铊和锡、用作供给氯的试剂,消毒剂,医药(防腐剂)。
溶解性:能溶于水,几乎不溶于苯、氯仿和乙醚,在乙醇中的分解。
储备液保存:-80°C, 6 months -20°C, 1 month
体内实验:1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.5 mg/mL (8.88 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% (20% SBE-β-CD in Saline) Solubility: ≥ 2.5 mg/mL (8.88 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。 3、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (8.88 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。
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.
