氟苯尼考纯度及其相关理化性能测定

氟苯尼考是氯霉素的氟化衍生物，为动物专用药，因具有抗茵谱广，吸收良好，体内分布广，无潜在再生障碍性贫血的副作用，使用安全，作为兽药和饲料添加剂在兽医临床上广泛应用。本文通过对所选取的氟苯尼考粉进行理化指标检测，为实际生产应用提供参考和依据。试验根据《中华人民共和国农业部公告600号标准》，对样品含量、熔点、酸度等进行检测。试验结果表明：测定的氟苯尼考含量为99．7％，其熔点、比旋度、酸度等检测指标均符合国家的相关规定。其产品性能稳定，具有广泛的市场应用价值。

Determination of Florfenicol Purity and Its Physico-chemical Properties

Florfenicol is a fluorinated derivative of chloramphenicol, as animal-specific drugs have a broad spec- trum antimicrobial, absorbing good, widely distributed in vivo, no potential side effects of aplastic anemia, safe in utilization, as a veterinary drug and feed additives in a the widely used veterinary clinic. In this paper, selected by florfenicol powder physical and chemical indicators to detect, for the actual production of reference and a basis for applications. Test according to ＂People＇s Republic of Chinese Ministry of Agriculture Bulletin No. 600 standard,＂ the content of the sample, melting point, acidity, such as for testing. The experimental results show that determina- tion Florfenicol concentration of 99.7%, its melting point, rotation, acidity and other indices are in line with the relevant provisions of the country. Stable performance of its products with a wide range of market value.
