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 1-(tert-Butyl)-4-(1-(2-cyclohexylethyl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one (CAS 878693-79-9), a certified reference material (molecular formula C23H33N3O, MW 367.53 g/mol) for analytical method development and quality control.
Structurally, 1-(tert-Butyl)-4-(1-(2-cyclohexylethyl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-2-one (C23H33N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 367.53 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.
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.
