Chemical Structure
Description
5-Methyl-2-(pyrrolidin-1-yl)aniline (C11H16N2) 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).
5-Methyl-2-(pyrrolidin-1-yl)aniline (CAS 91429-70-8) is a high-purity analytical reference standard with the molecular formula C11H16N2 and a molecular weight of 176.26 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
