Properties
Properties	【外观性状】白色结晶性粉末，有类似蒜的气味，味酸。有吸湿性，易溶于水或乙醇，不溶于乙醚、氯仿。在水溶液中呈酸性 (10g/L H2O中pH2-2.75)，mp101-107℃。本品为半胱氨酸的N-乙酰化衍生物，分子中含有巯基，能使黏蛋白肽键的二硫键(-S-S-)断裂，从而使黏蛋白链变成小分子肽链，降低粘蛋白的黏滞性，因此本品为黏痰、脓性痰、呼吸道黏液的溶解药。【熔点】106-108 °C(lit.)【比旋光度】-35.1 ºC (c=2,H2O)【折射率】24 ° (C=JPC Method)【储存条件】2-8°C【溶解度】H2O: 100 mg/mL with heating【Merck 】14,88【检测方法】HPLC,T,NMR,Rotation【BRN 】1724426
