Chemical Structure
Description
(2S,3R,4S,5S,6S)-6-(Bromomethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol (CAS 28528-87-2) is a high-purity analytical reference standard with the molecular formula C6H11BrO5 and a molecular weight of 243.05 g/mol.
Owing to a carbohydrate-derived structure, bromine substitution, (2S,3R,4S,5S,6S)-6-(Bromomethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
