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 3-(2-Ethyl-3,4-dihydro-2H-pyrrol-5-yl)-1H-indole (CAS 804439-82-5), a certified reference material (molecular formula C14H16N2, MW 212.29 g/mol) for analytical method development and quality control.
3-(2-Ethyl-3,4-dihydro-2H-pyrrol-5-yl)-1H-indole (C14H16N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
