Description

The occurrence of (2R,3R,4R)-4-((tert-butyldiphenylsilyl)oxy)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3-ol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,3R,4R)-4-((tert-butyldiphenylsilyl)oxy)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3-ol (CAS 308103-43-7), molecular formula C38H46O4Si2 and molecular weight 622.94 g/mol, is a CATO reference standard with documented purity and traceability.

(2R,3R,4R)-4-((tert-butyldiphenylsilyl)oxy)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3-ol (C38H46O4Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
