This article had studied the thermal characterization of the raw material and different fluconazole crystals, obtained through recrystallization with different solvents using thermoanalytical techniques (TG, DTA, DSC-50, DSC Photovisual, DSC-60) and Pyr-GC/MS. The results confirmed that the fluconazole volatilizes without decomposition until 250 °C. Pyr-GC/MS showed hexachlorobenzene like impurities in fluconazole raw material.
本文研究了原材料和不同氟康唑晶体的热特性,通过热分析技术(TG、DTA、DSC-50、DSC Photovisual、DSC-60)和Pyr-GC/MS,使用不同溶剂进行重结晶。结果证实,氟康唑在250°C之前不会分解而挥发。Pyr-GC/MS显示氟康唑原料中含有类似六氯苯的杂质。
