Chemical Structure
Description
The occurrence of (3R,4R,5S,6S)-6-methyltetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3R,4R,5S,6S)-6-methyltetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (CAS 30021-94-4), molecular formula C14H20O9 and molecular weight 332.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3R,4R,5S,6S)-6-methyltetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (C14H20O9) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), (3R,4R,5S,6S)-6-methyltetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
