Compared with other compounds in its class, the molecular weight of 309.41 g/mol gives 1-((1-Phenylpyrrolidin-2-yl)methyl)-3-(m-tolyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-((1-Phenylpyrrolidin-2-yl)methyl)-3-(m-tolyl)urea (CAS 1797643-38-9), a certified reference material (molecular formula C19H23N3O, MW 309.41 g/mol) for analytical method development and quality control.
Structurally, 1-((1-Phenylpyrrolidin-2-yl)methyl)-3-(m-tolyl)urea (C19H23N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 309.41 g/mol, it falls into the moderately-high-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.
