Chemical Structure
Description
CATO supplies tert-Butyl(((5S)-5-((4-fluorophenoxy)methyl)tetrahydrofuran-2-yl)oxy)dimethylsilane (CAS 220623-68-7), a certified reference material (molecular formula C17H27FO3Si, MW 326.48 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl(((5S)-5-((4-fluorophenoxy)methyl)tetrahydrofuran-2-yl)oxy)dimethylsilane (C17H27FO3Si) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 326.48 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
