Chemical Structure
Description
The molecular framework of 36393-83-6 3-(2-Hydroxyethyl)-2-{3-[3-(2-hydroxyethyl)-5-methyl-1,3-benzothiazol-2(3H)-ylidene]-2-methylprop-1-en-1-yl}-5-methyl-1,3-benzothiazol-3-ium bromide DTXSID80721842 (C24H27N2O2S2Br) is characterized by a steroid core, an amide group, a sulfone 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.
36393-83-6 3-(2-Hydroxyethyl)-2-{3-[3-(2-hydroxyethyl)-5-methyl-1,3-benzothiazol-2(3H)-ylidene]-2-methylprop-1-en-1-yl}-5-methyl-1,3-benzothiazol-3-ium bromide DTXSID80721842 (CAS 36393-83-6), molecular formula C24H27N2O2S2Br and molecular weight 519.52 g/mol, is a CATO reference standard with documented purity and traceability.
