Chemical Structure
Description
2-Methyl-4-(pyridin-2-ylcarbamoyl)-butyric acid (CAS 799258-40-5) is a high-purity analytical reference standard with the molecular formula C11H14N2O3 and a molecular weight of 222.24 g/mol.
The molecular framework of 2-Methyl-4-(pyridin-2-ylcarbamoyl)-butyric acid (C11H14N2O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
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.
