Chemical Structure
Description
2,3,4,6-Tetra-O-acetyl-β-D-mannopyranose (CAS 57884-82-9) is a high-purity analytical reference standard with the molecular formula C14H20O10 and a molecular weight of 348.30 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,3,4,6-Tetra-O-acetyl-β-D-mannopyranose is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,3,4,6-Tetra-O-acetyl-β-D-mannopyranose 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.
