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 (1R,2R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)cyclobutane-1-carboxylic acid.
CATO supplies (1R,2R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)cyclobutane-1-carboxylic acid (CAS 2580094-10-4), a certified reference material (molecular formula C20H19NO4, MW 337.37 g/mol) for analytical method development and quality control.
(1R,2R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)cyclobutane-1-carboxylic acid (C20H19NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
