Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [(2S,3R,4R,5R)-5-(benzyloxymethyl)-4-[tert-butyl(dimethyl)silyl]oxy-3-fluoro-3-methyl-tetrahydrofuran-2-yl] acetate.
[(2S,3R,4R,5R)-5-(benzyloxymethyl)-4-[tert-butyl(dimethyl)silyl]oxy-3-fluoro-3-methyl-tetrahydrofuran-2-yl] acetate (CAS 1583260-52-9), molecular formula C21H39FO5Si and molecular weight 418.62 g/mol, is a CATO reference standard with documented purity and traceability.
[(2S,3R,4R,5R)-5-(benzyloxymethyl)-4-[tert-butyl(dimethyl)silyl]oxy-3-fluoro-3-methyl-tetrahydrofuran-2-yl] acetate (C21H39FO5Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
