(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-2-cyclopentylacetic acid (CAS 187475-29-2), molecular formula C23H25NO4 and molecular weight 379.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-2-cyclopentylacetic acid (C23H25NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 379.45 g/mol, it falls into the moderately-high-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
