(1R,2S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)cyclopent-3-ene-1-carboxylic acid CAS 1212278-30-2

Description

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.

(1R,2S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)cyclopent-3-ene-1-carboxylic acid (CAS 1212278-30-2) is a high-purity analytical reference standard with the molecular formula C21H19NO4 and a molecular weight of 349.38 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (1R,2S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)cyclopent-3-ene-1-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
