2-((2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)ethyl)thio)acetic acid (CAS 180576-11-8) is a high-purity analytical reference standard with the molecular formula C19H19NO4S and a molecular weight of 357.42 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)ethyl)thio)acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
