Chemical Structure
Description
(2S,3S,4S,5R,6S)-3,4,5,6-tetraacetoxytetrahydro-2H-pyran-2-carboxylic acid (CAS 62133-77-1), molecular formula C14H18O11 and molecular weight 362.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2S,3S,4S,5R,6S)-3,4,5,6-tetraacetoxytetrahydro-2H-pyran-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (2S,3S,4S,5R,6S)-3,4,5,6-tetraacetoxytetrahydro-2H-pyran-2-carboxylic acid 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.
