January 2009 in “Yaowu fenxi zazhi” This study established a reliable method for determining residual solvents in Finasteride using gas chromatography.
January 2013 in “Zhongguo yaofang” This study established a sensitive and reproducible method for determining the levels of four organic solvents in finasteride raw materials, meeting the requirements of the Chinese Pharmacopeia.
January 2007 in “Journal of Instrumental Analysis” This study found that using headspace capillary gas chromatography effectively determined the levels of residual organic solvents, including chloroform and dichloromethane, in finasteride with good separation and detection limits.
January 2007 in “Chinese Journal of Analysis Laboratory” This study proposed a method to determine residual levels of dichloromethane and chloroform in finasteride using SPME-GC, reporting high linear correlation coefficients for both solvents.
