Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2S,3S,4S,5R,6R)-2-(Bromomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol (CAS 7404-26-4), a certified reference material (molecular formula C7H13BrO5, MW 257.08 g/mol) for analytical method development and quality control.
The molecular framework of (2S,3S,4S,5R,6R)-2-(Bromomethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol (C7H13BrO5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
