Chemical Structure

(2S,3S,4R,5R,6R)-2-(bromomethyl)-4,5-dihydroxy-6-methoxytetrahydro-2H-pyran-3-yl benzoate CAS 18929-88-9 chemical structure

Description

The occurrence of (2S,3S,4R,5R,6R)-2-(bromomethyl)-4,5-dihydroxy-6-methoxytetrahydro-2H-pyran-3-yl benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,3S,4R,5R,6R)-2-(bromomethyl)-4,5-dihydroxy-6-methoxytetrahydro-2H-pyran-3-yl benzoate (CAS 18929-88-9) is a high-purity analytical reference standard with the molecular formula C14H17BrO6 and a molecular weight of 361.19 g/mol.

Based on its molecular formula C14H17BrO6, (2S,3S,4R,5R,6R)-2-(bromomethyl)-4,5-dihydroxy-6-methoxytetrahydro-2H-pyran-3-yl benzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
