Chemical Structure
Description
CATO supplies (3aR,4S,5R,6aS)-4-(tert-Butyldiphenylsilyloxy)methyl-5-hydroxy-hexahydro-2H-cyclopenta[b]furan-2-one (CAS 84786-80-1), a certified reference material (molecular formula C24H30O4Si, MW 410.58 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3aR,4S,5R,6aS)-4-(tert-Butyldiphenylsilyloxy)methyl-5-hydroxy-hexahydro-2H-cyclopenta[b]furan-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
