Chemical Structure
Description
The molecular framework of (2S,3S)-2-(1-ethyl-1H-imidazol-2-yl)tetrahydro-2H-pyran-3-amine dihydrochloride (C10H17N3OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
(2S,3S)-2-(1-ethyl-1H-imidazol-2-yl)tetrahydro-2H-pyran-3-amine dihydrochloride (CAS 1820579-90-5), molecular formula C10H17N3OHCl and molecular weight 231.72 g/mol, is a CATO reference standard with documented purity and traceability.
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.
