(2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid CAS 959581-87-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid.

(2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid (CAS 959581-87-4) is a high-purity analytical reference standard with the molecular formula C28H23NO5 and a molecular weight of 453.49 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 453.49 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).

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.
