Chemical Structure
Description
CATO supplies ((2S,4R)-4-(Benzyloxy)-6-methoxytetrahydro-2H-pyran-2-yl)methanol (CAS 116563-00-9), a certified reference material (molecular formula C14H20O4, MW 252.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H20O4, ((2S,4R)-4-(Benzyloxy)-6-methoxytetrahydro-2H-pyran-2-yl)methanol contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
