Chemical Structure
Description
(2S,3R,4S,5S)-2-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 14520-32-2) is a high-purity analytical reference standard with the molecular formula C12H18O8 and a molecular weight of 290.27 g/mol.
The molecular framework of (2S,3R,4S,5S)-2-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate (C12H18O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures (2S,3R,4S,5S)-2-methoxytetrahydro-2H-pyran-3,4,5-triyl triacetate 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.
