Chemical Structure
Description
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 supplies 2-(2-Methyl-4,5-dihydro-1H-imidazol-1-yl)ethan-1-ol (CAS 695-94-3), a certified reference material (molecular formula C6H7BrO5, MW 239.02 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-Methyl-4,5-dihydro-1H-imidazol-1-yl)ethan-1-ol (C6H7BrO5) is characterized by a carbohydrate-derived structure, 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. 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).
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.
