Chemical Structure
Description
Based on its molecular formula C21H25N2O2Cl, Basicyellow11 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 372.89 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Basicyellow11 (CAS 4208-80-4), molecular formula C21H25N2O2Cl and molecular weight 372.89 g/mol, is a CATO reference standard with documented purity and traceability.
