Simplified 2,6-Di-tert-butyl-p-cresol Colorimetric Method for Unsaturated-3-keto Steroids
An improved modification of the original 2,6-DTBPC method for the determination of unsaturated 3-keto steroids has been developed. The presented technique features a simpler mode of operation, improved sensitivity, equivalent reproducibility, and extension of the original method to the analyses of 6...

description | An improved modification of the original 2,6-DTBPC method for the determination of unsaturated 3-keto steroids has been developed. The presented technique features a simpler mode of operation, improved sensitivity, equivalent reproducibility, and extension of the original method to the analyses of 6-fluoro 3-keto steroids unsaturated at both the 1 and 4 positions. Limited application to pharmaceutical dosage forms is also discussed. |
