Chemical Structure

(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-(tert-butyl)phenyl)butanoic acid hydrochloride CAS 403661-80-3 chemical structure

Description

The occurrence of (S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-(tert-butyl)phenyl)butanoic acid hydrochloride is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-(tert-butyl)phenyl)butanoic acid hydrochloride (CAS 403661-80-3) is a high-purity analytical reference standard with the molecular formula C29H31NO4HCl and a molecular weight of 494.03 g/mol.

(S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-(4-(tert-butyl)phenyl)butanoic acid hydrochloride (C29H31NO4HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
