Description

CATO supplies (2R,3S,4R)-4-((tert-Butyldiphenylsilyl)oxy)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3-yl acetate (CAS 342029-19-0), a certified reference material (molecular formula C40H48O5Si2, MW 664.98 g/mol) for analytical method development and quality control.

(2R,3S,4R)-4-((tert-Butyldiphenylsilyl)oxy)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,4-dihydro-2H-pyran-3-yl acetate (C40H48O5Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
