Chemical Structure
Description
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.
5-(1-Ethylpyrrolidin-2-yl)-4-methyl-2-(pyrrolidin-1-yl)pyridine (CAS 1352540-45-4), molecular formula C16H25N3 and molecular weight 259.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(1-Ethylpyrrolidin-2-yl)-4-methyl-2-(pyrrolidin-1-yl)pyridine (C16H25N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
