Chemical Structure
Description
The occurrence of Halobetasol Propionate is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Halobetasol Propionate (CAS 66852-54-8), a certified reference material (molecular formula C25H31ClF2O5, MW 484.96 g/mol) for analytical method development and quality control.
Based on its molecular formula C25H31ClF2O5, Halobetasol Propionate contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 484.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
