Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
(2R,3S)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,6-dihydro-2H-pyran-3-yl acetate (CAS 1638744-33-8) is a high-purity analytical reference standard with the molecular formula C24H30O4Si and a molecular weight of 410.58 g/mol.
The molecular framework of (2R,3S)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,6-dihydro-2H-pyran-3-yl acetate (C24H30O4Si) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (2R,3S)-2-(((tert-butyldiphenylsilyl)oxy)methyl)-3,6-dihydro-2H-pyran-3-yl acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
