Chemical Structure
Description
The occurrence of (((2R,3R,4S,5R,6R)-2-Iodo-6-(((trimethylsilyl)oxy)methyl)tetrahydro-2H-pyran-3,4,5-triyl)tris(oxy))tris(trimethylsilane) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(((2R,3R,4S,5R,6R)-2-Iodo-6-(((trimethylsilyl)oxy)methyl)tetrahydro-2H-pyran-3,4,5-triyl)tris(oxy))tris(trimethylsilane) (CAS 352432-46-3), molecular formula C18H43IO5Si4 and molecular weight 578.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (((2R,3R,4S,5R,6R)-2-Iodo-6-(((trimethylsilyl)oxy)methyl)tetrahydro-2H-pyran-3,4,5-triyl)tris(oxy))tris(trimethylsilane) (C18H43IO5Si4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
