Chemical Structure
Description
CATO supplies D-Ribofuranoside, methyl 2,3,5-tris-O-[(2,4-dichlorophenyl)methyl]- (CAS 677299-16-0), a certified reference material (molecular formula C27H24Cl6O5, MW 641.19 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, D-Ribofuranoside, methyl 2,3,5-tris-O-[(2,4-dichlorophenyl)methyl]- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 641.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
