Chemical Structure
Description
3-[1-(4-ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl]-3-oxopropanenitrile (CAS 554407-01-1), molecular formula C17H18N2O and molecular weight 266.34 g/mol, is a CATO reference standard with documented purity and traceability.
3-[1-(4-ethylphenyl)-2,5-dimethyl-1H-pyrrol-3-yl]-3-oxopropanenitrile (C17H18N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
