Chemical Structure
Description
The molecular framework of N-(2-bromo-5-(((tert-butyldimethylsilyl)oxy)methyl)pyridin-3-yl)pivalamide (C17H29BrN2O2Si) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
