Chemical Structure
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.
CATO supplies (9H-fluoren-9-yl)methyl (S)-(2-((tert-butyldimethylsilyl)oxy)-3-oxopropyl)carbamate (CAS 2454243-91-3), a certified reference material (molecular formula C24H31NO4Si, MW 425.59 g/mol) for analytical method development and quality control.
Structurally, (9H-fluoren-9-yl)methyl (S)-(2-((tert-butyldimethylsilyl)oxy)-3-oxopropyl)carbamate (C24H31NO4Si) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 425.59 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.
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.
