Chemical Structure
Description
The occurrence of (11β,16α,20S)-9-Fluoro-11,20-dihydroxy-16-methyl-3-oxopregna-1,4-dien-21-oic Acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (11β,16α,20S)-9-Fluoro-11,20-dihydroxy-16-methyl-3-oxopregna-1,4-dien-21-oic Acid (CAS 50764-02-8), a certified reference material (molecular formula C22H29FO5, MW 392.46 g/mol) for analytical method development and quality control.
(11β,16α,20S)-9-Fluoro-11,20-dihydroxy-16-methyl-3-oxopregna-1,4-dien-21-oic Acid (C22H29FO5) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
