Chemical Structure
Description
CATO supplies (((9H-Fluoren-9-yl)methoxy)carbonyl)glycyl-D-leucine (CAS 2171289-23-7), a certified reference material (molecular formula C23H26N2O5, MW 410.46 g/mol) for analytical method development and quality control.
Structurally, (((9H-Fluoren-9-yl)methoxy)carbonyl)glycyl-D-leucine (C23H26N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 410.46 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
