Chemical Structure
Description
4-(Dimethylamino)-2-(m-tolylamino)nicotinonitrile (CAS 339102-29-3), molecular formula C15H16N4 and molecular weight 252.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Dimethylamino)-2-(m-tolylamino)nicotinonitrile (C15H16N4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
