Chemical Structure

(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((4-methoxybenzyl)thio)-3-methylbutanoic acid CAS 159618-54-9 chemical structure

Description

The occurrence of (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((4-methoxybenzyl)thio)-3-methylbutanoic acid is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((4-methoxybenzyl)thio)-3-methylbutanoic acid (CAS 159618-54-9), molecular formula C28H29NO5S and molecular weight 491.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-((4-methoxybenzyl)thio)-3-methylbutanoic acid (C28H29NO5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
