Chemical Structure
Description
(Cyclopentyl(3,4,5-trimethoxybenzyl)carbamothioyl)glycine (CAS 656816-06-7) is a high-purity analytical reference standard with the molecular formula C18H26N2O5S and a molecular weight of 382.47 g/mol.
The molecular framework of (Cyclopentyl(3,4,5-trimethoxybenzyl)carbamothioyl)glycine (C18H26N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
