Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(((9H-Fluoren-9-yl)methoxy)carbonyl)thiomorpholine-3-carboxylic acid 1,1-dioxide.
CATO supplies 4-(((9H-Fluoren-9-yl)methoxy)carbonyl)thiomorpholine-3-carboxylic acid 1,1-dioxide (CAS 2137447-97-1), a certified reference material (molecular formula C20H19NO6S, MW 401.43 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H19NO6S, 4-(((9H-Fluoren-9-yl)methoxy)carbonyl)thiomorpholine-3-carboxylic acid 1,1-dioxide contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
