Chemical Structure
Description
(2R,3R,4S,5S,6R)-2-((benzoyloxy)methyl)-6-bromotetrahydro-2H-pyran-3,4,5-triyl tribenzoate (CAS 14218-30-5), molecular formula C34H27BrO9 and molecular weight 659.48 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,3R,4S,5S,6R)-2-((benzoyloxy)methyl)-6-bromotetrahydro-2H-pyran-3,4,5-triyl tribenzoate (C34H27BrO9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures (2R,3R,4S,5S,6R)-2-((benzoyloxy)methyl)-6-bromotetrahydro-2H-pyran-3,4,5-triyl tribenzoate 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.
