Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 179.22 g/mol gives 4-Morpholinophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Morpholinophenol (CAS 6291-23-2) is a high-purity analytical reference standard with the molecular formula C10H13NO2 and a molecular weight of 179.22 g/mol.
Structurally, 4-Morpholinophenol (C10H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 179.22 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
